Did life only start once?

Scientists believe life likely emerged multiple times on early Earth through abiogenesis (life from non-life), but all current life shares a single Last Universal Common Ancestor (LUCA), suggesting other early life forms were outcompeted or wiped out before leaving lasting evidence, possibly due to Earth's harsh early conditions or subsequent mass extinctions. We know our life stems from one lineage due to shared genetics, but the possibility of "shadow biospheres" or "second genesis" events remains a fascinating area of research, with some scientists searching for clues in ancient rocks.
