More than that. Ancients are millions of years old. They originally came from the Ori Galaxyto the Milky Way then to the Pegasus Galaxy then back to rthe Milky Way Galaxy. The Stargates is as old as Destiny which means the Destiny originated slightly after they came to tthe Milky Way Galaxy. That us because we saw sketches of the Stargate in Ark of Truth.
The Four Races is actually hundreds of years old which means the last of the Ancients died off some time in Renaissance
They left the Milky Way originally for Pegasus a million years ago because of some plague. Then came back ten thousand years ago.
