Is that Faith?

I had an informal discussion with an acquaintance several years ago about aliens.

"I would stop believing in God" he replied.

"Why?" I asked him.

"Because then Evolution would be true and then we wouldn't need God!" he responded with vigor.

This little innocuous conversation got me thinking how much faith did that indicate he had?

Shouldn't we as believers be of the mind that we always find a way to believe? Isn't that FAITH?
