Look at what’s out there.

"Does Christianity exist in alien planets?"

An interesting question.

There are countless trillions of solar systems in the universe. There could be numerous civilizations with creatures more or less like us. If this is true, would these planets have the same god bullshit problem we have?

Christians think their loving God is only interested in this middle-of-nowhere planet in a vast universe. And that's ridiculous. If Christians knew how to think they wouldn't be Christians.

So altogether I can’t believe the special stories that’ve been made up about our relationship to the universe at large because they seem to be too simple, too connected, too local, too provincial. The “earth,” He came to “the earth”, one of the aspects of God came to “the earth!” mind you, and look at what’s out there. It isn’t in proportion!

Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people.
