@hannorein If we only do things that have value, we lose the humanity that was granted to us hundreds of thousands of years ago when the first humans put their hands on a cave and spit ochre at them. What kind of life is it if all we ever do is look at the ground?

Dreams and the search for knowledge is what drives us to see what's over the next hill. Yearning for answers to questions unanswerable is an inherent part of what it means to be human.
