I found out recently that Michelangelo's painting of Adam on the Sistine Chapel depicts him without a belly button. I had never noticed this before and it makes sense that neither Adam nor Eve would have belly buttons, not having been born in the usual way.
Then I realized all the first animals were created rather than born, according to the religious views of the origin of life. So... the chicken definitely came before the egg. How come this isn't a widely accepted view of the question? I mean, lots of people who ask this question believe in God and are religious. I can't believe I never thought of it before. I get why scientists and atheists would still question which came first, but I would also expect them to acknowledge the religious point of view, if only to reject it. I've never heard anyone use a religious point of view to answer this philosophical question.
