Distant past

Billions of years ago

More than 10 billion years ago

Just "before" the Universe, as seen by Voyager's crew

The crew of Voyager view the birth of the Universe

• The universe is formed in one or multiple expansion phases that scientists called "Big Bang(s)". Federation cosmologists still debate in the 24th century on the datation of the universe and the causes of its birth. (VOY: "Death Wish", "The Omega Directive", "Latent Image", "Good Shepherd")

Current real-world scientific evidence indicates the age of the universe to be 13.799 ± 0.021 billion years.
In VOY: "Latent Image", the Doctor said that the primordial atom burst occurred 20 billion years ago.
In VOY: "Good Shepherd", an engineer said that the cosmos was 16 billion years old {which was the estimated age during the filming of the episode}. In the same episode Cosmologist Mortimer Harren said he was about to disprove Schlezholt's Theory of Multiple Big Bangs and had to demolish Wang's Second Postulate to do it. But Kathryn Janeway considered that Wang's second postulate has more lives than a cat.
According to VOY: "The Omega Directive", Federation cosmologists had a theory that the Omega molecule once existed in nature for an infinitesimal period of time at the exact moment of the big bang, some even claimed Omega was the primal source of energy for the explosion that began our universe, but others thought it was just a creation myth like any other.

• The birth of the Universe represents a hideout for members of the Q Continuum. The USS Voyager was briefly transported here by Quinn in order to escape Q, but he too had once used this hideout and was thus able to find the ship. (VOY: "Death Wish")

No datation was given in that episode. Quinn only mentions that there's actually no universe outside.

---

Current real-world scientific evidence indicate that most galaxies are more than 10 billion years old, including the Milky Way and the Andromeda Galaxy.

According to an okudagram from TNG: "The Royale", showing data about planet Theta VIII, its age was "7.2e10×10¹⁰ solar years", i.e., 72 billion years old.

9 billion years ago

• Hundreds of protostars collapsed in close proximity to one another forming the astronomical phenomenon later known as a black cluster. (TNG: "Hero Worship")

In 2368, the USS Enterprise-D crew indicate that the Black Cluster was formed nine billion years ago.

5 billion years ago

• The star Sol begins to form out of nebular dust and interstellar gases. (VOY: "Death Wish") ^{(citation needed • edit)}
• Female Q is born. (VOY: "The Q and the Grey")

In 2373, she was angry being tossed aside by Q for someone five billion years younger (Kathryn Janeway). Considering the time traveller nature of the Q, this comment could refer to a duration rather than a datation.

4.5 billion years ago

• The Guardian of Forever was asked its last question until 2267. (TOS: "The City on the Edge of Forever")

It told Captain James T. Kirk and Spock that it had awaited a question "since before your sun burned hot in space."

Current real-world scientific evidence indicate that Sol was formed 4.57 billion years, and that Earth was formed 4.54 billion years.

Ancient humanoid

• The Progenitors seeded the oceans of many worlds with DNA codes, directing the evolution of life towards a physical pattern similar to their own. The varieties of lifeforms that carried this seed code to fruition include the Humans, Vulcans, Klingons, and Cardassians, and likely many other humanoid species of the galaxy. (TNG: "The Chase")

Analysis made by the USS Enterprise-D crew in 2368 estimate the genetic program to be over four billion years old.

4 billion years ago

• Q and the female Q begin their romantic involvement around this time. (VOY: "The Q and the Grey")

In 2373, they were involved for about four billion years. Considering the time traveller nature of the Q, this comment could refer to a duration rather than a datation.

• The planet Pollux IV forms in the Beta Geminorum system. (TOS: "Who Mourns for Adonais?")

USS Enterprise sensors in 2267 indicate an approximate age of four billion years.

3.5 billion years ago

France billions of years ago in an alternate past

• On Earth, in a region later known as France, amino acids combine to form the first proteins. In an alternate timeline, an anti-time eruption prevents the formation of life, fulfilling Q's verdict for Humanity. (TNG: "All Good Things...")

Q refers to three and a half billion years ago, "give or take an aeon".

According to current real-world science, there is evidence that suggests life took hold on Earth already between 3.8 and 4.1 billion years ago [1] and flourished in the oceans by at least 3.7 billion years ago. [2]

2 billion years ago

• Civilization on Tagus III exists as of this time. (TNG: "Qpid")

In 2367, Q proposed Picard to see Tagus as it was two billion years ago, and commented that "they really knew how to party back in those days".

It was not elaborated whether this civilization was already Taguan or some preceding species.

1 billion years ago

A possible depiction of a Slaver

• The Slaver Empire is the master of all intelligent beings in the Milky Way Galaxy. The Slavers and all of their subjects are exterminated in a massive war which caused all intelligent life to re-evolve. (TAS: "The Slaver Weapon")

In 2269, history of the Slaver Empire was considered sketchy. The stasis boxes were the rare source of information the Federation had at their disposal.

Millions of years ago

400 million years ago

• In the Devonian period, Eryops, the last common ancestor of cold-blooded and warm-blooded organisms, lives on Earth. (VOY: "Distant Origin")

According to real-world science, Eryops lived some hundred million years later during the Permian period.

300 million years ago

• An alien ship of an insectoid race is invaded by a magnetic organism. Trapped in orbit of Questar M-17, the crew destroys their own ship to prevent it being carried to other worlds. (TAS: "Beyond the Farthest Star")

In 2269, retro analysis of the ship's spectra dates it as having been in orbit here for slightly more than 300 million years.

87 million years ago

• The D'Arsay civilization launches the archive of their culture. (TNG: "Masks")

In 2370, USS Enterprise-D encountered this object in sector 1156 and calculated, based on its origin in the D'Arsay system, that it spent 87 million years drifting in space for over two sectors.

65 million years ago

• A mass extinction occurs at the end of the Cretaceous period on Earth when a comet impacts the planet, wiping out the dominant reptile superorder, the dinosaurs, among others. (VOY: "Distant Origin"; ENT: "Azati Prime")

In 2154, Jonathan Archer indicate that a comet hit his world around 65 million years ago, causing a mass extinction, most of the reptiles died out and mammals became the dominant species.

In 2373, USS Voyager crew discussed about the hadrosaur who vanished when a mass extinction occurred at the end of the Cretaceous Period, and asked the computer to run a genome projection algorithm if the hadrosaur had continued to evolve over the last 65 million years.

• According to the Distant Origin Theory, some of Earth's dinosaurs belonging to the hadrosaur genus survive the mass extinction. Although the dominant reptile superorder was almost wiped out, these surviving dinosaurs continue to develop, likely on a secluded, later destroyed landmass. Sometime thereafter, they possibly become one of the first interstellar species in the galaxy when they leave Earth and travel to the Delta Quadrant, laying the foundation for the Voth civilization. (VOY: "Distant Origin")

While Dr. Forra Gegen suggests this hypothesis for the origin of the Voth, Chakotay later theorizes that the Voth's ancestors left before the extinction event, the impending catastrophe being what motivated them to do so in the first place.

50 million years ago

• An amphibous lifeform goes extinct. (TNG: "Genesis")

When Deanna Troi was affected by Barclay's Protomorphosis Syndrome in 2370, she de-evolved into an amphibious lifeform which became extinct over 50 million years ago. Considering her mixed heritage, no information was given on the origin of this lifeform (Betazed or Earth).

20 million years ago

• Now considering themselves a race indigenous to the Delta Quadrant, the recorded history and identity of the Voth dates back to around this time. (VOY: "Distant Origin", "Friendship One")

In 2373, the Ministry of Elders was reluctant to deny 20 million years of history and Doctrine just because one insignificant saurian has a theory.

10 million years ago

• The humpback whale evolves on Earth. (Star Trek IV: The Voyage Home)

6 million years ago

• The creators of Vexilon ascend to the fifth dimension, but forget to update its operating system in the process. (LD: "In the Cradle of Vexilon")

5,997,626 BC

• Vexilon's operating system was updated this year. It would not be updated again for another six million and seven years. Vexilon apparently viewed this year as a "good year." This partially had to do with the harvest. (LD: "In the Cradle of Vexilon")

1 million years ago

• On Earth, the ancestors of Humans begin to distinguish themselves from their primate ancestors by their intelligence and reasoning skills. (TOS: "A Taste of Armageddon") ^{(citation needed • edit)}
• Construction of the vast city around the Guardian of Forever, stretching out to the horizon of its' planet. (TOS: "The City on the Edge of Forever")

Tricorder analysis in 2267 revealed the ruins to be on the order of 10,000 centuries old.

Indeterminate

• The inhabitants of Organia evolve into beings of pure energy. (TOS: "Errand of Mercy")

Ayelborne said that his people had evolved beyond the need for physical bodies "millions of years ago."

• The ancient Bajoran civilization begins to flourish. The ancient Bajorans are renowned for their accomplishments in architecture, science, mathematics, philosophy, and the arts. (TNG: "Ensign Ro")

Jean-Luc Picard stated that the ancient Bajoran civilization was flourishing "when Humans were not yet standing erect". According to real world science, the evolution of Human bipedalism can be traced back to several primate species between 4 and 7 million years ago, and the emergence of Homo erectus to about 2 million years ago.

• Pliocene epoch on Earth. (VOY: "Basics, Part I")

In 2372, Hanon IV was an M-Class planet in a Pliocene stage of evolution comparable to Earth several million years ago.

According to real-world science, the Pliocene epoch spans from 5.33 million to 2.58 million years on Earth.

Hundreds of thousands of years ago

600,000 years ago

In 2364, the T'kon civilization had been extinct for 600,000 years by the 2360s according to Federation databases.

• The humanoid ancestors of Arretans colonize the galaxy. Their colonists may have caused, or influenced, the rise of intelligent life on Vulcan. (TOS: "Return to Tomorrow")

In 2268, Sargon indicated that their vessels were colonizing this galaxy six thousand centuries prior.

500,000 years ago

• Arretan civilization is destroyed in a massive civil war when the atmosphere is ripped from Arret. Only a few survivors escape by preserving their consciousnesses in a cave deep below the surface. (TOS: "Return to Tomorrow")

In 2268, scans of the USS Enterprise revealed that the planet's atmosphere was ripped away by a cataclysm, about a half million years ago.

• The planet Exo III becomes uninhabitable after its sun begins to go dark. The inhabitants resettle beneath the surface and construct androids to serve them. (TOS: "What Are Little Girls Made Of?")

Hirogen relay station

• The subspace network which will be later claimed by the Hirogen is constructed. (VOY: "Message in a Bottle", "Hunters")

In 2374, USS Voyager encountered a relay station whose age was estimated at least 100,000 years old.

• The ocean planet, later home of the Monean civilization, is created by extracting all water from a class M planet and containing it inside an immense force field. (VOY: "Thirty Days")

In 2375, USS Voyager crew found a field reactor whose age was at least 100,000 years old.

• In Africa on Earth, the /Xam Abathwa tribe gathers to share a story about a girl who created the milky way. In one later told version of the story, the girl belonged to a group of primitive farmers afraid of the night, until the girl encounted an alien. (DIS: "Brother"; ST: "The Girl Who Made the Stars")

This story is set "a thousand centuries ago" (before 2230s and 2257).

Indeterminate

• The population of Talos IV is largely wiped out in a war. Forced to live beneath the surface, the Talosians develop their mental powers, while neglecting their technological knowledge and skills. (TOS: "The Cage", "The Menagerie, Part I", "The Menagerie, Part II")

In 2254, Vina said the war occurred "thousands of centuries ago".

According to Star Trek: Star Charts, p. 34, the Talosians become warp-capable 500,000 years ago. According to the All Our Yesterdays: The Time Travel Sourcebook, the Talosian wars occurred 400,000 years ago.

• A Sphere-shaped lifeform that died in the mid-23rd century dates back to this era. It records everything it sees and experiences starting around this time as well, including data on countless civilizations. (DIS: "Project Daedalus")

In "An Obol for Charon" (2257), initial scans suggest the sphere is only one hundred thousand years old, but this seems to have been revised to hundreds of thousands years by Project Daedalus.

• According to Guinan, the Borg began their evolution into cybernetic beings thousand of centuries before the 2360s. (TNG: "Q Who")

In 2365, Guinan told that "They're made up of organic and artificial life which has been developing for thousands of centuries." No information was given on the source of that information.

Star Trek: Destiny presented a different point of origin for the Borg.

Tens of thousands of years ago

28,000 years ago

• On Earth, the Neanderthals become extinct. (ENT: "Dear Doctor") ^{(citation needed • edit)}

25,000 years ago

• The stone tablet city in Bajor is abandoned, sediments bury the ruins, and eventually the ancient city of B'hala is built on top. (DS9: "The Reckoning")

In 2374, archeologists estimated that this site was abandoned some 25,000 years ago.

22,000 years ago

Circa 20,000 BC

• The first of at least 947 archaeological expeditions is conducted at the ancient ruins on Tagus III. (TNG: "Qpid")

10,000 years ago

Circa 8,000 BC

• The machine-god Vaal is built on Gamma Trianguli VI. (TOS: "The Apple")
• The civilization on Sigma Draconis VI, by this point at its technological peak, advanced well beyond 23rd century Federation capabilities, experiences a catastrophic glacial age.

• A path on a Delta Quadrant planet was said to be cut out by unknown spacefarers. The path endured into the 24th century, when it was used by Mikhal Travelers who had an outpost on the planet. (VOY: "Darkling")

In "The Dogs of War", Weyoun 8 euphorically claims that "the Dominion hasn't surrendered in battle since it was founded ten thousand years ago." This seems to contradict Weyoun 4 in "To the Death", who states "The Dominion has endured for two thousand years [...]."

In DS9: "Little Green Men", Nog states that it "took [ten thousand years] to establish the Ferengi Alliance", which implies it dates back to 8000 BC or earlier. This might also imply that Gint, the first Grand Nagus and original author of the Rules of Acquisition lived at this time, if he is considered the founder of the Alliance.

Indeterminate

Earth is visited by aliens who settle in the region near Greece and the Mediterranean, where they are worshiped by the Greeks as gods. (TOS: "Who Mourns for Adonais?")

In 2267, Apollo said they knew Earth well 5,000 of your years ago. This would place the Greek Gods on Earth at the time of the Minoan civilization and the Tiryns culture of Ancient Greece. However, the earliest references to Greek mythology historically date from around 900BC, which would seem to have been well after when Apollo states the Greek gods had left Earth.

The Star Trek Encyclopedia, 4th ed., vol. 1, p. 125 dated this event to around the year 3000 BC.

Sarpeidon experiences an ice age. Zarabeth is later exiled to this time period, and Spock and Leonard McCoy are briefly stranded here as well. (TOS: "All Our Yesterdays")

In 2268, Platonians stated that millennia ago, they managed to escape just before their sun went nova. They transported themselves to Earth during the time of Socrates and Plato {5th century BC}, where their leader liked Plato's ideas. 2,500 years before 2268 {circa 232 BC}, they arrived on a barren rough-hewn planet they called Platonius.

Parmen ("present philosopher king") and Philana were born in the 1st century BC, so they are obviously not from the previous generation that met Plato.

Indeterminate

• Kalandan constructed an artificial planet. During its construction, a deadly disease organism was accidentally created, killing all the outpost's inhabitants. Supply ships servicing the outpost inadvertently transported the disease back to the Kalandan homeworld, which presumably led to the extinction of their species. Before her death, Losira enabled the outpost's automated defenses to protect it until the day when more Kalandans would arrive to secure it. (TOS: "That Which Survives")
