Translation:How important is humanity's existence?
Some would say that the importance of human existence is an exclusively human concept, so if humanity stops existing the question loses its meaning. Then again, those people don't get invited to parties for a reason.
Science is leaning toward the idea now that time holds so much in common with the other 3 dimensions of space that each moment may never actually end with respect to higher dimensions, and may exists permanently etched onto a 4-D space-time continuum.
If that is the case, then meaning is never truly lost, and every moment exists on for a type of eternity, like pages in a comic book.
Actually, it's a Me quote. I've used the "some would say" pattern in other comments relating to Existentialism 101.
Well, they told me in the philosophy lesson to be prepared for the destiny one...
