Man I was so excited about this thread. I really think that is a good question.
Unfortunately it is so strongly under te shadow of religion.

IMO it is much more reasonable to say that the universe existed forever than to say that god existed forever and created the universe a little while ago.

But please lets talk about the question. Could something every come from nothing?
If once there was nothing and now there is something. How could this come to be?
If nothing was to ever change to something would it not need something, maybe a force, to make it change?
