That which does not exist, non-existence of nothingness can't cause or create something because it doesn't exist; besides, we have evidence only for causation and no hard evidence of something from nothing.
Other atheists try a different tactic with nature. They say there was an infinite regress of cause and effects, but if that were true, you would have had an eternity to come into being before now so you should have already happened.
Therefore, nature or the universe needs a cause outside of itself, outside of time and space, being uncreated by the uncreated Creator God.
Very simple so anyone can understand.
