Well, you have access to one universe, without a clear explanation as to its presence.
You just said we've all seen the poofing. Which is it?
Sorry, the universe was the "it" I was referring to. I'm not sure "poofing" is the most helpful descriptor of... anything. However, I'm interested in the basis of anyone's claim to know how the universe came into being. A sample set of one doesn't give you a lot to work with.
The universe (meaning "everything that exists") either spontaneously began from nothing, or was always there.
"It was made by a God" is incoherent; The closest you can get to a coherent claim from that position is "It was once just a God, and that God made everything else". But then you have to ask where God came from; And if your claim is that God always existed, or that God began to exist from nothing, you need to explain why you feel the need for the extra step, in the complete absence of any evidence that it is necessary - and also explain why you don't feel the need for more than one un-evidenced and utterly pointless extra step.
God is a concept that adds exactly zero to our understanding of origins, while requiring assumptions for which there is zero basis
