Since I saw something about the beginning of the universe, I'll post the generally accepted scientific approach:
Since we need a beginning for our primitive minds to understand, let's say we take the big bang beginning(NO, I'm not going to discuss whether it's correct or not, I'm merely going to say what is generally accepted). Then we go BEFORE that big bang. Because the Big Bang was the utter beginning(as we just established) before that, there must've been nothing(If you don't like that, take some other point as a beginning, and go back from THAT). And if there is nothing, there are no laws to hold the nothing, meaning that anything can happen. That is the most difficult concept to grasp, if there is nothing, there are no laws, and anything can happen. THAT is the currently generally accepted scientific explanation.
ANd it doesn't even form a conflict with God. If from the nothing, God came, then there is no conflict. If God came and made the Big Bang: no conflcit. If the bible isn't supposed to be taken literally: no conflict!!
