There is a God. Everything in our universe is in exact alignment to allow human life. There were so many other possibilities, that if one thing was different, we would not have life on this planet. Do you really think this was just some freaky conincidence? It is more likely that a God desined this perfect set of circumstances than it just popping up out of no where. Last time I checked man did not make earth. Man did not create the stars. Did all this happen from nothing?

God is not a continginet being like humans. He is a Necessary being, meaning He is self-exsisting. He needs no cause, He is the cause, the first cause.
Everything is in motion, everything. For it to be in motion, something must put it in motion. There must be a first mover. That is God.
