I've always been a little perplexed when religious folks tell me I must think life is meaningless/worthless because I believe in biology rather than deities. Life is beautiful in the intricacies of how biology works, how we've evolved, how creatures can hang on in a niche they are poorly suited to hold because they have one little trait that gives them a slight advantage. That's awesome, in the true sense of the word. Every time a new piece of the puzzle is found, expanding our understanding of how we went from bacteria to fish to amphibians to reptiles to birds and mammals it is humbling. I realize we are *nothing* compared to nature and subject to our own biology. This chunk of rock we call home will be spinning long after we're gone, replaced by something that can adapt better and more quickly to the Earth as a living system. That's amazing, and it makes life worth more to me than it would if I saw this all filtered through a vain sense of my own immortality.
