God does or does not exist with or without our approval.
For all things there exists a source, with each source converging back unto one; the source of all life, apart from which there is no other, is therefore absolute, and contains no contradiction.
If God is the source of all things then he is the source of all life and is therefore living and absolute; apart from whom nothing exists. If he is not the source of all things, and is therefore not living, and not absolute, then the word God is just a name for rejecting someone’s idea of him.
If we are not our own source, then we are not absolute and therefore not God, who does not require our acknowledgement or approval to be our source.
