Sure, other versions of God, an old man with a beard sitting in heaven, are much harder to prove! But which version is the right version? Who decides which definition of God is the right definition? Are we allowed to pick our own definition? Or are we not allowed to pick or own definition? If we are not allowed to pick our own definition of God, who will define God? Your cat?

If we are allowed to pick our own definition of God, then I don't see how you can argue about his existence before knowing what that person actually means by "God".
This is called pantheism, "God is in everything, everything is God".
