Both egyptians and i agree there is God. Rest is an Argument between theists as to how many.
But we both agree that you are deluded.
Nope it is not just argument between theists. It is a solution to this conundrum.
So either your God is real or the Egyptian God (or for that matter any other God) is real, or both are fictitious.
Because your God states, there is no other God but him, I am sure Egyptian God must be stating something similar.
