I got into a recent discussion about destiny, and was asked for my thoughts...
Ask yourself if it is really irrational if human beings all around the world share the common notion that there is something bigger and more sacred than themselves? That there are places where our ancestors and loved ones go? Is that ignorant and irrational if there perhaps is a complex in our brain that wires us to imagine such a thing? I think even atheists want to believe in something, they just need more proof. I do not think that everything happens for a reason, but I feel that there are currents and flows that lead in a deterministic kind of way. I don't know if we have destinies, and I'm glad that I don't know; it leaves more room for free will, but at the same time encourages the fact that we may have the ability to be parts of something significant. And I think that is what humans want. We want our lives to be significant...that our struggles, works, and experiences matter...to know we left a mark. This ties back into the belief in something that you can't see, because since most of us are unsure that we are significant while we are living on earth, we hope that there is something beyond us that will resonate and give us the ability to look back and see that we did matter.
