No, not even on earth, the only place you have observed it is on earth..... It wouldn't matter if water existed on every planet in the universe. Presence of water does not equate to presence of life. Lipid bilayers have only been observed with life, not as a naturally occurring form separate from life.
Of course they self assemble, that's what they have been programmed to do. They are life, not inorganic compounds.
They haven't got any of the steps figured out. Every single process is incompatible with the next process. The conditions favoring one are disastrous for the next. You'll have to do better than evolutionary PR and the dead belief of spontaneous generation.
"Belief in spontaneous generation of certain forms of life from non-living matter goes back to
Aristotle and
ancient Greek philosophy and continued to have support in Western scholarship until the 19th century."
