God?

what is God? is he real or is he a fragment of man's imagination to help him forget his regrets and mistakes blaming a so called man named jesus for healing a man on the sabbath? why should someone be punished for helping someone in need. All i think happen is the deciples or jesus' friends needed someone to take the fall for them so they betrayed him and made the bible to make it look like he did something nobel because they felt bad. If God is real then let him show it if he brings someone back to life that claims he is Jesus and can heal people then i might believe.
