Agnostic of Christian cultural background here: I think part of what is meant is that <i>murder</i> was caused by original sin. Sure, death from other causes would already have occurred in any case, but murder is still part of our world because we evolved as K-strategists in desperate competition with other members of our species; that original sin that we are struggling to leave behind, had to be the case because such competition is what drove us to evolve intelligence in the first place.<p>As for creation myths, we have a document written several thousand years ago which says the universe began in a flash of light and developed through several stages of increasing complexity, which I think is pretty impressive given that it wasn&#x27;t until the mid-20th-century that science established this is indeed the case.
