Also, I should mention, that you are right that some people are deceived and think that they are following God but in reality they are not. That is why the Bible is pretty clear about the fact that people will say "There is the Christ" but to be careful not to just follow anyone. And the Bible warns of the Anti-Christ that will come and do miracles and even deceive the "elect if that were possible."
How do we know what is right and wrong? We are supposed to "test the Spirits." If we know that the character of God is good and the fruit of the Spirit is Love, joy, peace, patience, kindness, gentleness and self-control we can use that as the measure in which to gauge where someone's heart really is and if something is from God or not. You will know a "tree by it's fruit" the Bible says.

if this is supposed to be a response to me than i dont think you understood what i was saying. it was an argument for how it is imposable for the existence of good to be proven because even if some apparently supernatural creature floats down from the sky and performs seemingly imposable miracles, you still have no way of knowing whether its actually god and not an alien, or a hallucination, or a life form from another dimension ect...
even if there was a god, you could literally never know that for sure, and nothing god could ever do could allow you to know that for sure.
Most Christians are very confident that they "Know" without a doubt God is real and they believe in Jesus so much so that they are even willing to risk their lives to be a Christian in places that do not allow for people to. The reason is because the Spirit of God reveals Himself to us in a way that we cannot deny Him in our hearts. The song Amazing Grace says, "I once was blind but now I see." There is truth in that. It is a spiritual thing that cannot be explained or logically understood. It has to be experienced. The only way for it to be experienced is for the person to go to God him/herself and pray and ask God to reveal himself. Until then it cannot happen.
