Then that would render all scientific advancments usless. After all, we'd just start from the stone-age again anyways, so what's the point of learning more?

P.S - I don't buy into us destroying ourselves. Information would have survived somehow... if there was a huge war today, i'm sure we all be burying our textbooks underground for future generations. Of course if we destroyed ourselves, then there would be no future generation. Unless you wait a few billion years for the monkeys of today to become the humans of tommorow.
