If I'm not mistaken HIV wasn't around until about 1964 in humans, and there we didn't know about it in the monkey population before then.
Tell me how physics disproves God? Those subjects are all forms of understanding. And how do you know that they're true any more than the Bible is. You weren't there in the period that it talks about. Maybe it's a world wide conspiracy that the machines we're plugged into outside of this computer simulation have fed us so we don't know the past? You're theoretical babel only disproves your own credibility.
