Of course, we are facing the most primal and philosophical question that a human being can ask himself throughout his existence. Various theories or hypotheses have been postulated that try to explain abiogenesis, that is, the origin of living beings from inert matter formed by organic compounds.
An example of these postulations is panspermia, which proposes that the first microorganisms arrived on Earth transported by small stellar bodies. Beyond speculation, this type of hypothesis is subjected to strict laboratory tests. The results are being at least promising.
