The formation of the earth - words... super
Molecular structure of the ribosome 30S subunit from Thermus thermophilus. Starting with the work of Carl Woese , molecular studies have placed the last universal common ancestor LUCA between Bacteria and a clade formed by Archaea and Eukaryota in the phylogenetic tree of life. The result suggest that the LUCA was anaerobic with a Wood—Ljungdahl pathway , nitrogen- and carbon-fixing, thermophilic. Its cofactors suggesest dependence upon an environment rich in hydrogen , carbon dioxide, iron , and transition metals. Its genetic code required nucleoside modifications and methylation. LUCA likely inhabited an anaerobic hydrothermal vent setting in a geochemically active environment. It is likely that the ancestral ribosome was composed entirely of RNA, although some roles have since been taken over by proteins. the formation of the earth

I apologise that, I can help nothing. But it is assured, that you will find the correct decision.
Quite right! I like your idea. I suggest to take out for the general discussion.
Fantasy :)
What does it plan?
Yes, really. And I have faced it. We can communicate on this theme. Here or in PM.
