I remember in the seventies a scientist warned about trying to make contact with alien life. He said that they would probably be so much farther advanced than us we would appear insignificant, like Ants are to us.
If aliens exist they probably already know of our insignificance, indeed they may have given us a helping hand.
It's strange all the old and ancient religions all believed their gods lived in the sky. They called them father or the all father. Ancient people wouldn't be able to comprehend what they were seeing, but the clues are there. Apollo in his chariot of fire, Jesus, born by the direction of a new star, and going up on a cloud. A lot of the things built in ancient times all point to the sky, or they can only be seen to full effect from the air.
We could have come this way before, the Eskimo's believe that their ancestors were carried there by a huge bird with iron wings.
If god exists he could be an alien, but I believe he is the Sun.
Very thought provoking. It's good to ask questions like this rather than repeat parrot fashion things that you have been taught.
