the fundamental building blocks of life are prevalent in space, and strengthens the argument that life in the universe may be common rather than rare.
In evolutionary thought exaggeration is taken to new heights. The notion that glycine found on a comet suggests that the fundamental building blocks of life are prevalent in space is simply absurd. Perhaps those building blocks are indeed out there, but this finding gives little reason to think so.
Far more staggering, however, is the bizarre notion that the presence of glycine (or even all the biochemicals one can imagine) tells us anything about the prevalence of life in the universe. It would be like finding metal samples and concluding that the presence of automobiles in the universe may be common rather than rare. This is embarassing.
