Question for next time: We now know (to the best of our knowledge) that most of the heavier elements come from kilonova events, but are these elements heavier than iron actually necessary for life? I.e., are there any known instances of life that don't require those heavier elements and could thus originate without having a nearby kilonova event in its past?
I am certain this can happen. And if several are born that way we could have micro galaxies. The intergalactic version of Monaco. I have read some stories that I am almost sure is AI written. I have also read some stories by really bad authors. These authors, AI and human, are in competition.
