The Miller-Urey Experiments have already established that the molecules for life formation are quite simple to synthesize.
You would think "astronomers/astrophysicists" would have familiarized themselves with this. Apparently not.
In the General Theory of Stellar Metamorphosis life has its origins where it currently resides, on the star which has evolved to the point of being able to produce and host it. In the Miller-Urey Experiment a vast multitude of chemical compounds including many different types of amino acids were produced as a result. No interstellar nonsense is required.
