This is a Gish gallop - so I have to ask if this will be a long gallop thread if you are a creationist, or are you interested in the science despite letting your personal incredulity affect your reading?
Meanwhile, and I have already said that, scientists are curious, excited and in high activity regarding the possibility of extant or extinct life on Mars. And organics means carbon compounds more complex than CO2 where biomolecules are a major but not ell encompassing category [
https://en.wikipedia.org/wiki/Organic_chemistry#Biomolecules ]. Many organic compounds are produced in astronomical or geological environments, and distinguishing between, say, volcanic or meteorite produced organics is an ongoing concern for martian (and other) astrobiology.
I have already noted that photosynthesis does not come into early evolution. Alkaline hydrothermal vents on the other hand seems to have been where the universal ancestral lineage evolved. So there are consistent evidence from trees and other biology: not photosynthesis, but ocean chemotrophy.
There is also no principle problem in vent evolution, which is ongoing with modern life. On the contrary experiments show sugars nucleobases and nucleotides are formed and polymerized in rapid heat/cold cycling. PCR is after all how we amplify sequences! [Too many references to give at once, and you don't seem concerned about the sources/science anyway.] The missing compound type is amino acids, but they were produced all over in the else acidic environment and especially nearby acidic hydrothermal vents in plate tectonic oceanic ridge systems (where oceanic plates form from upwelling mantle material). It is an odd claim to say that condensation reactions happen here or there, but in cells as well as under water they occur in gels. Mind that the small group of biochemists that push for wet/dry fresh water pool chemistry are neither motivated by biology or geology, or has a current broad acceptance as promising explanation for early evolution.
