Christian/Jewish/Muslim: God made the world (in about seven days), making it mostly as we see it now.
Atheist: Singularity "exploded" into the Big Bang, creating stuff that made the materials needed to create Earth.
Christian/Jewish/Muslim scientist: God did the Big Bang.
Pastafarian: Flying Spaghetti Monster (cheese be upon Him) created the world while constantly drunk on beer.
Me: What world? The only world that exist is what I think about. It goes away when I die.
