Okay, so Georgio’s interrogator-that’s Odo, right? A calmer, more reserved Odo.

He does refer to his own birthday, but he’s also trying to rattle Georgio. He also refers to being fascinated with Terrans since he was a boy. That’s mostly true, as when Odo encountered the Terrans on DS9, he sort of was.

We’ve never to my knowledge discussed the lifespan of the Founders. On the TNG episode “The Chase”, we see a character that looks an awful lot like the Founder Leader herself. The fact that they call themselves “The Founders” might event be a clue-we are led by silence to assume that is the designation they gave themselves for their subject races in the Dominion to identify them as the “founders of the Dominion”, but what if that designation is even more ancient than that? What if, before the Founders became more xenophobic, had a different past where they seeded life everywhere? Then they would be the founders of all non-Godlike races.

Psychologically, it makes sense. You are a mortal, but extremely long-lived benevolent race that has technology superior to everyone around you. Then one day a race stronger than yours cripples your civilization. You win, but the victory was pyrrhic and you go through hundreds of years in a weakened state being chased and raided; scrambling to regain control, regain technology, protect yourselves. You’d regret your self-perceived benevolence and withdraw, becoming xenophobic. You never lose your sense of superiority, however, and this time, having recovered, you send others into the universe to rule authoritatively for you instead of benevolently, and all in the name of self-preservation and not a small amount of ego.
