You can very easily prove God exists; all you must do is determine what constitutes as God. "I say God is the universe, and the universe is real, therefore God is real"--that sort of thing. But as far as the biblical descriptions of God go, no, he's a paradoxical impossibility invented by people with no knowledge of the limits of the space we inhabit.
On the other hand, the many definitions of the word "God," show that God might be something like infinitely greater than we are... at least in some ways. So why would we think that something like God is or might be "a paradoxical impossibility invented by people with no knowledge of the limits of the space we inhabit?" After all, nobody knows the limits of the space we inhabit. Science and scientists are gaining understanding, but they are a far distance away from knowing all that there is to know. Maybe, just maybe, God knows and uses it all. The Bible descriptions could easily be not only accurate, but fairly understating about the greatness of God, and it is simply mankind that is extremely weak in understanding nature and the universe around him.
Or maybe god doesnt exist. I mean the bible is the stupidest book ever, in its time yeah it may have looked like an incredible book but now we know that a lot of things it says are false like the earth age, the earth being flat, the pi number and many many more
