We can concieve a God who can create the Universe with no or little evil in it. Since such a God would be greater ifgreat, if that God exists in both mind and reality, therefore such a God indeed exists in relaity, and is greater than the God of this current Universe.
But we don't have less evil Universe. We have the Universe where comparatively more suffering exists. So this argument cannot establish a maximally good God, because maxiamlly good God would have created a better Universe. So here problem of evil seems to disprove ontological argument. Is this argument acknowledged and are there any criticisms to it?
