God is a handy way of explaining things that we don't understand.
There have been Sun gods, Thunder gods, Rain gods etc
That is exactly what the bible is all about...it's authors were writing about things they didn't understand.
Genesis featured a Rainbow
It's quite amusing really.
There is no physical evidence of God or Jesus, God has never spoken to anyone or taken over all the TV's in the world to deliver a message.
I quote:
Nothing in Christianity is original. The pre-Christian God Mithras - called the Son of God and the Light of the World - was born on December 25, died, was buried in a rock tomb, and then resurrected in three days. By the way, December 25 is also the birthday or Osiris, Adonis, and Dionysus. The newborn Krishna was presented with gold, frankincense, and myrrh. Even Christianity's weekly holy day was stolen from the pagans.
The religion will, and has already started to die out.
