Science is what we humans use as a way of learning about the world, even the universe around us using methods based upon logic. The problem is, logic, and therefore science, has at least one glaring flaw that i cannot get around(maybe someone can prove me wrong so I can sleep better at night). If you see a cat, logically you know that the cat must have been born, and that it must die as well. So if we look at the universe, it must have come from somewhere, and there must be an end.
So we run into a problem.
a) Everything cannot have a beginning, there must be something that has existed, and always will, which flies in the face of everything I know about science and logic.
b) Everything must have a beginning, which flies in the face of everything I know about science and logic.
Either way, science and logic have a major flaw, so since both A and B are equally impossible, we are in a sort of quandry arn't we.
