because disproving omnipotence requires omnipotence
How does that work? Why do you think unlimited poweris required to see the flaw in the idea of unlimited power.
Omnipotent = all powerful
All powerful = nothing is impossible
If God creates an object/being that he is incapable of destroying then he does not have sufficient power to destroy the item, thus he is not omnipotent.
If God is incapable of creating such an object/being then clearly there is a limit to what he is capable of, thus not omnipotent.
I'm not challenging your belief in God, and should he exist then he would undoubtedly be the most powerful force/being in existance, all I'm saying is that the word omnipotent cannot accurately be applied to anything, not even God.
