The very idea of an omnipotent God is flawed to start with:
Even if this God had the power to create so huge a rock that he himself would not be able to lift it, that would be proof of his lack of omnipotence. Yet, even in that case, it would be he himself who thus makes himself non-omnipotent, so even this non-omnipotence would be HIS doing, so he can still claim to be omnipotent.
It comes to such logical absurdities.
