If you’re talking specifically about the Abrahamic God, sure. But if it’s about the existence of any higher being, then there’s no contradiction here.
Anything that you would call a “god”.
If I give an ostensive definition, I would say it includes the beings like the Abrahamic god, or Olympian gods, and exclude humans, animals, bacteria, the planet we live on, and objects we handle in our day to day lives. I’ll tentatively draw the line at any being that is not bound to the laws of physics as we understand them today.
Why exclude humans, animals and bacteria? How about Sun? Jesus Christ? God-King Jayavarman II? A cat? Very small spirit of tiny stream? A holy stone (stone is not a human, nor animal or bacteria, a lot of stones were worshipped in various forms and meanings in history)? A tree chewed by pilgrims? Invisible Hand of the Market?
Incredibly arbitrary definition again constructed to wriggle your way from any concrete statement.
