Gee, I think you would have burned Copernicus at the stake.
It is the absolute height of arrogance to believe that we are alone in God's vast universe.
To paraphrase, Jesus said something along the line of "My Father's house has many rooms."
The Bible, at the time, was written for people far more primitive than us. The thought of man walking on the moon would have been unthinkable in the days Our Lord walked the Earth.
