We don't know where it began or if it's been here forever but we can't just say the only alternative is a creator.
I'm not saying that the universe came from nothing since we don't have an example of nothing to come to such a conclusion.
It's such a profound and difficult question and I don't think that we'll ever know or maybe we will one day but in the mean time we can't buy into the belief of something supernatural whenever we don't know the answer.
it's okay to say I don't know, it's the person who claims to have all the answers that we should be worried about.
