You don't naturally find zebras and horses in the same geographic area. There were, until recently (about 45,000 years ago, if I remember correctly), other species of hominids; at one point there were simultaneously fully-modern, or nearly so, humans in Africa, Neanderthals in Europe and the Middle East, and even a few surviving homo erectus in parts of Asia. Once homo sapiens began to spread out from Africa, the other species disappeared because they couldn't compete. (Neanderthals, who appear to have been very close to us in brainpower, hung around until quite recently.)
And here I thought *I* was old.
Sure is a lot of wiggle room in these numbers. And usually when I'm shown a corpse of Bro, it's not even a whole limb or even a whole skull. I remember my first disillusionment with the evolutionists was when I actually found out how little in the way of corpus was in all this delecti--enormous theories built around such small holy relics. And that's a curious thing in and of itself--where're the bodies buried?
