I mean, that would be a bit like asking Chris Columbus in 1491, "" Hey Chris, you know, what happens if it turns out that there's a continent between here and Japan, where you're sailing to, what will be the consequences for humanity if that turns out to be the case? "" And I think Chris would probably offer you some answer that you might not have understood, but it probably wouldn't have been right, and I think that to predict what finding E.T. 's going to mean, we can't predict that either.
