We KNOW that? Or do we just “assume” that?
Did we come here in one piece? Did we evolve? Were we created?
(But don’t get me started!!)
I have no interest in the evolve/created debate.
But there are creatures that are extremely old (roaches, snails, whatever) from the earliest of fossil records that exists today.
Large portions of the genome of these “clearly original” creatures is similar to current day human DNA.
Heck, there is “junk” DNA in corn and other plants that tracks human DNA just fine.
So, regardless of the “evolve” or “create” camp, we’re as native as the rest of the stuff on this planet.
