If you refer to an anthropocentric God, that is, a god conceived in the image and likeness of man, but with super powers, no, I do not believe in him. This idea of God is expressed by the most multitudinous religions, like Christianity or Islam.

I agree with the ancient Greek Xenophanes of Colophon that if animals had a mind and also could paint, they would paint God with the form of an animal.

I do not deny that there is something like a "God", but if there is, it is surely something much more complex than what is expressed by anthropocentric religions.
