Let me give you a scenario.
You are a 1 in relation to God
For arguments sake I am a 1 regards a different god that contradicts yours in some way
For arguments sake lets both accept that one of us is actually correct
We both have absolute and equal knowledge, conviction and "evidence" (in your terms) in our knowledge.
We cannot both be correct
Therefore one of us is deranged
How can we find out who is right and who is deranged?
If it is impossible to differentiate between the two then all your arguments so far are contradictory as they apply equally to the truth of either position.
