It is impossible for there to exist a being who is omniscient, omnipotent, and omnibenevolent.

I was expecting with so few rounds an explosion of intellectual prowess of irrefutable statements! I got a blurb man! Just stating the "Problem of Evil" as you did is not a good approach, as you will see below. << 1) An All-loving, or infinitely good God cannot overrule freewill without committing evil. It is all-loving and infinitely good to allow "beings" to have a freewill. His divine Will within His Divine "Good" attribute would restrict His further action. 2) The first being that had freewill from God did the first act of evil. He convinced others to do evil. He convinced humans to do evil. 2) The evil in the world is perpetuated upon people who reject the guidance and transcendent moral value system of the all-loving and infinitely good God. He tries to instruct all beings about what is good. This is done by showing both Evil and Good. The measuring stick and the concept of the measurement. They reject this by using their freewill. 3) God will right all of the wrongs by judging those people who chose to perpetuate evil in the world. He will punish the evildoers for their deeds. 4) God has enemies who perpetuate evil outside of the Free Will of Man by utilizing their own free Will. God also does not overrule his enemies' use of their free will even though they overrule man's use of freewill... compounding evil. 5) These enemies will also be judged and punished according to their deeds. Once the above scenario is taken into account the logical possibility of an Infinitely Good / All Loving God coexisting with the presence of evil becomes quite possible. As a "preemptive rebuttal"… to prove that overruling freewill would indeed be a greater good, my opponent would have to prove that wiping humans of all brain function and utilizing them as cattle or devices is "good and loving" above whatever harm they may do. Additionally he would have to prove that "in the end" all wrongs would indeed NOT be righted and allowing free will would NOT play out a greater good in a future existence. << The coherence of my opponents claims of what God "would do/should do" breaks down in the following: If Hitler was killed by God as a baby by a "not so random disease" to avoid the tragedy of the Third Reich, God is called an unjust evil baby killer or powerless to cure Hitler. If Hitler is allowed to live…. God is called either powerless to stop Hitler's slaugher machine or He is evil to not stop Hitler's slaughter machine. You can see the problem with my opponents claims is that neither He (nor I) are in a good position to know what God should do and when. This directly poses the possibility that an all-knowing God knows exactly what needs to be done and when to do it. This is all guided by a Maximally supreme, All Loving , infinitely Good, all knowing God. Conclusion: Strictly speaking I have shown that the resolution is entirely possible, and logically coherent and my opponent stands refuted. He would have to completely and without a shadow of a doubt disprove all of my claims above and he himself would have to assert an amount of knowledge about all possible events/all possible scenarios/all possible persons etc… that would be "akin" to a God claim himself….. This is something he is unable to ever do.
