There is no empirical evidence. You can't just point to something and say that is evidence of X. You first have to demonstrate there is a connection between the evidence and X. I can't pick up a bit of sandstone from the ground and claim it is evidence of snakes. In order to demonstrate the connection between the empirical evidence, you first must determine what are the properties of God. Otherwise, you could be staring at the evidence and not know. Or just assuming something is evidence on the basis that you want it to be. If you don't know the properties, you can't make the connection with any evidence.
The existence of the universe
is the empirical evidence for God's existence. What else could the evidence possibly be? Define God and the connection is manifest. To define God is to extrapolate precisely what the empirical and rational evidence for God's existence is.
I think, therefore I am. I think about God, therefore he exists. Easy peasy.
I made no such argument.
Rather, define God. The idea of God is that of the Creator. Creator of what? The universe, that's what!
I say again:
The existence of the universe is the empirical evidence for God's existence. What else could the empirical evidence possibly be? Define God and the connection is manifest. To define God is to extrapolate precisely what the empirical and rational evidence for God's existence is.
Finally, both the empirical and rational evidence tell us that the universe began to exist; i.e., the universe is not the eternal ground of existence!
Easy peasy.
