Unless life can change without a universe. We are drifting in order to answer questions put to me. If I stick strictly to the topic, I can’t answer the questions that drift away from the topic.
I understand the challenge of organizing the discussion. However, if new independent issues arise then they should be in separate threads. You can answer any questions just by creating a new thread for them.
Life can change in whatever way it does however the universe came into being. So how planets formed has no bearing on biological evolution.
You may, if you wish, start a thread that is not discussing the issue of planet formation but show how it does have some bearing evolution. Be very cautious about going down this path. You have no idea of the issues you will raise.
