I cannot explain the creation of the universe, but the first life most likely came from a high energy lightning strike and then evolution.
There is no god. He has shown no signs of existence. You don't have a soul, your body was "generated" by a series of instructions from sperm and egg.
Religion was created to keep order in the early world because life was much harder and suicides were more common. After all if there is no god, what is the point of living?
