Sabemos que la vida comenzó hace al menos 3.500 millones de años, porque esa es la edad de las rocas más antiguas con evidencia fósil de vida en la tierra. Estas rocas son raras porque los procesos geológicos posteriores han remodelado la superficie de nuestro planeta, a menudo destruyendo rocas más viejas y creando otras nuevas (lo siento si es un amor incorrecto, marque como más inteligente si es correcto).

La pregunta del cómo empezó la vida en la Tierra es una de las más difíciles (e interesantes) que se pueden plantear. De hecho, el origen de los seres vivos encierra varias cuestiones clave: ¿cuándo ocurrió?, ¿pudo producirse más de una vez?, ¿cómo fue la transición entre la química y la biología?, ¿tuvo lugar en la Tierra o fuera de ella? Y, a medio camino entre la ciencia y la filosofía: ¿fue fruto del azar o de la necesidad?

La investigación experimental sobre el origen de la vida comenzó en la década de 1950, con el trabajo de dos científicos pioneros en una disciplina llamada química prebiótica: Stanley L. Miller y Joan Oró. Las pruebas acumuladas desde entonces nos indican que la vida probablemente comenzó hace unos 3.800 millones de años, sólo 700 millones de años después de la formación de nuestro planeta. En el gran laboratorio de química que era la Tierra primitiva se sintetizaron las primeras moléculas orgánicas, que fueron organizándose progresivamente para formar otras más largas y complejas.
