Calls me a retard after saying:
And if you're going to say "I meant only if they could all be alive," then state that in the post. Don't expect everyone else to read something dumb and know you didn't mean it to be dumb.

You completely missed the entire point. You're an idiot. OP is taken from River Out of Eden by Richard Dawkins as well FWIW.

No, he called you a retard because 30 generations back, assuming you have no inbreeding or adultery, you DO have 1,073,741,824 people in that single generation. See, if he were counting ALL of the ancestors, it would be 2^30+2^29+2^28+...+2^0. But he's talking one generation. 2^30.
Start with yourself. That's 2^0. 1. Now, how many ancestors do you have in your parents' generation, one generation back? 2^1. That's two. How many in your grandparents' generation, two back? 2^2. That's 4. 30 generations back? 2^30. 1,073,741,824. That large number is not a sum. It's a single generation.
Exponentiation: Multiplication's tricky friend.
