The films depicting life and heroics of Superman have Biblical themes in them. Superman has something in common with Moses and Jesus.
Moses is left in a basket to float on Nile. The daughter of Pharaoh finds him. She hires the mother of Moses to take care of Moses. After three months Moses grows up at Pharaoh’s palace. Superman is an infant when he is sent to earth from Krypton by his parents. He grows up on earth.
Jesus is the saviour, so is Superman. Both do good. Jesus raises the dead. Superman brings Lois back to life by going back on time. Jesus performs miracles. Superman’s deeds are miraculous. Jesus suffers, so does Superman. Jesus conquers death by resurrection. Superman does not die.
