These scientists get too caught up in the chemistry of life. The wonder of life is the intelligent information encoded in the molecules. That information doesn’t just come out of nowhere.
“That information doesn’t just come out of nowhere.”
Francis Crick, co-discoverer of DNA reasoned that it was too complex to have “just happened”, and that an intellegent being created it. He proposed the idea of other civilizations blasting out the code into space - “pansperma”. Of course that just begs the question of where did those aliens get the code?
And more recently they have learned, it isn’t just the way the code is arranged, it is also how it is folded and packaged.
