I know it's not canon and the ages of the Ultras was given long before Tiga and the Heisei era. In the manga the Plasma Sun went of Ten thousand years before the first series, so take ten thousand years of all the Showa Ultras and they would still be some thousands of years old. Also whether it's canon or not is not the point, at some point it was and that's how Tsuburya envisioned the Ultras' human ancestors which is why I took reference from the Manga.
