In the vast expanse of the cosmos, the search for life beyond Earth is a captivating endeavor. Among the myriad of challenges, one of the most intriguing is deciphering the subtle signs that might indicate the presence of prebiotic chemistry, the precursor to life as we know it. This is where the concept of proto-biosignatures and planetary geochemical metabolism (PGM) comes into play, offering a novel approach to understanding the potential for life's emergence in the universe.
