Having a recorded and civilized history reaching back far beyond the beginning of space travel,[4] their original homeworld forgotten, and early history of Humans was lost to their scientists in the depths of millennia. Whatever the original homeworld was, it was universally accepted that Humans evolved on one of the Core Worlds near the galaxy's center. Humans were among the few sentient species in the galaxy whose homeworld was unknown, the Ryn, Yoda's species and the Baragwins being some other examples.
I don't know how canon it is but the place they came from is Earth?
Apparently not:

Battlestar did this plot well imo, it’s never really been important in SW
Life began out there.
Maybe it wasn't canon but I remember a story with Han going back to Earth looking for something and discovers the bones of Indiana Jones.
Technically Hell is canon because Han tells someone to go to Hell at some point in the movies lmao
