Do you know if NASA has evidence of alien life?

Yes, I do know the answer to this. It’s no, NASA has no evidence of alien life to date. We only have theories and speculation, but without evidence there is no proof of alien life anywhere else in the universe other than good ol’ Earth.

That being said, most scientist believe life probably exists elsewhere in the universe, but until we actually find even a fossil of a microbe of alien life, there’s no evidence to date.
