To be clear, Satan certainly is a being, but certainly nothing like God.
I'm not demanding anything, as these are not MY ideas. The existence of Satan is clear and explicitly documented in Holy Scripture from Genesis to Revelation. He, in the New Testament, tempted Christ Himself on more than one occasion. That Satan exists is a foregone conclusion (not a debatable point of contention) of Catholicism, Protestantism, Judaism and even Islam.
The only way I'm "wrong" is if you're not a Christian, a religious Jew or even a Moslem.
You are wrong. There is no Satan as an independent being. The only independent beings are us humans.
