"Show me where the Bible says God didn't put life anywhere but earth. It doesn't say he did, but it doesn't say he didn't, either."

Correct. Some, however, interpret the "sheep in other folds" as referring to life elsewhere.

The universe is an awfully big place that's been going on for an awfully long time. It is sheerest human vanity to think that we're alone.

Specifically:

John 10:16 (KJV):

And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
