Men In Black

"Fifteen hundred years ago, everybody knew that the Earth was the center of the universe. Five hundred years ago, everybody knew that the Earth was flat. And fifteen minutes ago, you knew that humans were alone on this planet. Imagine what you'll know tomorrow."

-Agent K, Men in Black

I can honestly say I never thought of all quotes, my favorite one would be from Men in Black, but here we are. This quote shows to me how little we actually know, but it's comforting because it simultaneously makes me feel that anything could happen, we just may not yet have the knowledge to understand that yet.
