There are two essential questions that drive every human being:
Is this all I am?
Is this all there is?
The most feared answer to both of those questions — the one we refuse to accept:
Yes.
The answer we want to believe and that drives us to push harder, dig deeper, keep searching, and achieve things once believed impossible. The answer that has led to every discovery and breakthrough. The one that is at the center of every faith. The one that makes us human:
No.
