Sorry to disappoint you. I'm not going to argue with you about whether these links were about "energy-generating systems" or not. I suppose everyone can choose their words more carefully to be more accurate, and I did not in this post.
Thanks for taking the time to write a thoughtful comment.
Despite all our current knowledge, it's still true that there is a lot we don't know about biology. I'm not saying we'll never figure it out, but given the current state of biology, it is still "mysterious" and a lot of questions about the origin(s) of life remain.
If you think you know or have all the answers, more power to you....
