Thanks for sharing! I'm personally a fan of the idea that life has always existed, meaning we have always existed as well. It's very cool to listen to someone like Roger Penrose expressing his thoughts on what possibly happened before the big bang. In my opinion, everything in Nature repeats, and nothing is so special that it cannot happen again when we understand the concept of infinity. People who favor the idea of believing in God might be against such a notion, but I think it's worth exploring along with all the philosophy that can emerge from it.
