Creators will sometimes sometimes try to make it sound like something is positively ancient by stating that it is ten thousand years old. One common example is the supposed sinking of Atlantis. Many cultures have a distinct word for 10,000 that is often used to refer to any indefinite large number — in English, for example, it's "myriad". Currently, the development of agriculture is estimated as having occurred ten thousand years ago. And the earliest example of print is much younger than 8,000 BC.
- First Comics' Mars by Mark Wheatley and Marc Hempel has the advance team of terraformers lose contact with Earth, and decide to let their robots reshape the planet Mars on automatic while they place themselves in stasis pods for ten thousand years, in hopes that Mars will be habitable by then.

- Dune by Frank Herbert takes place in the year 10,191 AG, after the Spacing Guild was founded and the Imperium established.
- On Gor by John Norman years are measured by locally significant events such as Year X of King Y's reign. For the sake of stability many locations also date their years in CA, "Contassa Ar" or "from the founding of Ar" (Gor's largest city-State). In the first book it's 10,119 CA.
- In Heinlein's Magic, Inc. Ditworth is sentenced to ten thousand years of imprisonment by Satan for being defeated with white magic. Fraser notes that it's like the demonic equivalent of six months in prison.

- In Mighty Morphin' Power Rangers, Rita Repulsa was locked up for 10,000 years in a "Space Dumpster" on the moon, as she helpfully reminds viewers in the Opening Narration sequence before every season 1 episodenote . This currently serves as the page quote.
- Interestingly, Witch Bandora's imprisonment in Kyoryu Sentai Zyuranger was even longer. To be precise, 170 million years.
- Power Rangers Jungle Fury's backstory also goes back to a great war 10,000 years ago; Wild Mass Guessing regarding whether the two incidences are in fact one and the same, and 10,000 years ago is just a rough estimate, was initially very popular.
- Babylon 5: When Delenn explains the Shadows and the First Ones to Sheridan, she tells him the last time they made open war with each other was 10,000 years ago. The last war fought by the younger races against the Shadows, on the other hand, was a "mere" 1,000 years ago.
- Star Trek: Deep Space Nine gives two figures for the Dominion's age. One is this trope, the other is a 'mere' over two thousand years (given the context it's possible it simply took the Founders some eight millennia to get from planning the Dominion to actually implementing the Dominion).

There ain't nothing in this world that I don't know
I saw Peter, Paul and Moses
Playing Ring Around the Roses
And I'll lick the man who says it isn't so
- The more recent catastrophic events in Warhammer 40,000 happened around the thirtieth millennium, 10,000 years earlier (the Fall of the Eldar and the rise of Chaos).

- Warcraft: The first time the demonic Burning Legion invaded Azeroth was ten thousand years ago, during the War of the Ancients. This also became an important date for many related characters, including the entire night elven race (who were immortal and have been alive since then). Illidan Stormrage's time spent since the War of the Ancients was a little bit different and defines his character, as he had been imprisoned in a lightless prison since then. He tells us this himself during the cinematic:
Imprisoned for ten thousand years. Banished from my own homeland. And now, you dare enter my realm? You are not prepared.

- In the sequel series, The Legend of Korra, Harmonic Convergence is an event that occurs once every 10,000 years. During this the spirit of light Raava and the spirit of darkness Vaatu battle to decide whether the next 10,000 years will be those of light or those of darkness.
