I don't see how the Universe always existed means God doesn't exist.
Anyway, if God didn't exists then there's no way you can convince me that life was created by accident. Oh I forgot - you said everything always existed. This to me is harder to believe than the existance of God. But I suppose we all have to have faith in something, be it God or the supposition that the Universe and everything within it was always there. Each to their own.
