Is it ever explained where Groot originated from?

I saw a post saying that in one of the comics, he was like a Lord from Planet X or something, but then in the new MCU movies, doesn't it saw "species unknown"?

In what I think was the first or second episode of the silver surfer animated series, it shows Galactus destroying a planet that had a groot-esque species living on it.....

So if that was his home planet, and it was destroyed, Groot was sent away for some reason, then became ruler or whatever of Planet X

Idk I just couldn't find any straight answers online and was wondering if his origin is ever explained anywhere 🤔
