The concept of God as the sole creator of everything.Which concept of God? There are many different concepts. The Jewish concept has not yet sent the Messiah. The Hindu concept is different again, as is the Buddhist concept.
You're sitting in judgement on the Christian God who will kill you too, and judge you. I suggest you've got the wrong approach. You don't grasp whom you're dealing with.The Christian God is not a man, I agree, however He kills far too many people and He used to demand animal sacrifice. That changed for some reason, which is a small improvement. Buddhist morality does not follow a "might makes right" rule as the Abrahamic religions treatment of their God seems to do.
I'm not talking about "gods."Buddhists can do that is they want, though animal sacrifices to their chosen god(s) are not allowed. Fruit, flowers and light are acceptable.
I think I do.You have no idea of Buddhism.
Why should we believe him? May be he was just lying, or talking about release from inner demons that had been plaguing him. Release from demon possession isn't "full enlightenment" even if it entails some kind of enlightenment.You are wrong. The Buddha attained full enlightenment at age 35. He died at age 80. You do not need to die to attain enlightenment. Enlightenment can be found here and now.
