Depends on what do you mean by "God". If you think God is a person, who sends good people to heaven and bad people to hell - then no. His rules are impossible to follow. If they were true, no one would ever go to heaven.
This is the best formulation of a proof that God in the Bible/Quran/Other religions is man made. Probably has a logo too.
“The God of the Old Testament is arguably the most unpleasant character in all fiction: jealous and proud of it; a petty, unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser; a misogynistic, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully.”
There are forces in the Universe that we do not understand yet. It's a proven fact that everything has a magnetic field. We are all connected. Literally. Science has proven that. Planets even have auras. So again - depends on your concept of god. But to believe in Jesus, or Satan is hilarious.
Just because god has been misinterpreted by religions doesn't make the concepts of jesus or satan any less true. Jesus did exist, nature always has a way of rising one person in the position to discover, share and rebel against a greed based society to the farthest extent. When you are in that position and reach that state of consciousness, you realize a few things: death is inevitable, living in fear of death is illogical, pain is a manifestation of ego, if you live a life of spreading peace you will feel no pain when you die, you have nothing to lose and everything to gain by beholding the position of jesus.
Jesus is beyond a universally singular person. Jesus is a soul, the spirit of god. Jesus is the one. He is neo, it matters not what form he takes.
Satan is also not a singular being. Satan is the concept of the material world, ego, negativity.
This spiritual universe has been personified in order to be portrayed in terms humans can comprehend. God is well beyond any one humanoid being. God is light, god is love.
