"And what, I ask, is the size of the earth in comparison with the vastness of the heavens above?" Bellarmine marvels in 1618. "Astronomers claim that it is like a mere point, and they are right. We see that even when the earth comes in between, the sun's rays reach to the stars at the end of the firmament as if the earth were nothing at all. And if every star of the firmament is greater than the whole earth, as scholars generally believe, and still these stars seem tiny specks to us because of the of the almost infinite distance, who can grasp in thought the size of the heavens where so many thousands of stars shine? Please consider now, my soul, if the world is so great, how great is he who made the world? [I]f another world were created, God would fill it too, and if there were many worlds or even an infinite number of worlds (emphasis added), God would fill them all."

Hummm! Like maybe even "life on other planets?" Wow! Cool!
