re: What if Life owed everything to...chance?
I disagree that life has no meaning. What we can do, and it’s a lot when you think about it, is the best job possible to propagate our species into the future. That’s the true meaning of life.
I like the part of Desiderata “You are a child of the universe, no less than the trees and the stars; you have a right to be hereâ€.
