Argument for God from time and contingency

There is something
This something comes into existence and goes out of existence
There was a time when there was nothing.
There was a time somethings started to exist.
 From nothing , nothing comes
The something (the universe) was brought into being by something else.
That something else should transcend the universe and should be outside the universe(outside matter ,space and time), Otherwise it would need another being which is absolutely independent or necessary as opposed to contingent or dependent.
This absolutely independent (necessary) being [which brought into existence something when there was nothing] is God.
