I don't believe anything "created" the universe
Matter cannot be created or destroyed. All the matter we have today has always been here....none has been created out of nothingness
You cannot "create" an atom out of thin air
If it is possible to create matter...Why hasn't any been created in the last billion years?
Why can't an atom be created in a lab?
That's right, you believe in something infinity greater than humans, and infinity greater than the universe, but it's still as simple as a rock. That's not really any better than saying nothing created the universe.
Implicit in the Big Bang model is the continued creation of matter/energy. Expansion of the universe pulls apart gravitational bound bodies, and therefor requires a constant supply of energy that didn't previously exist.
