Abiogenesis is the formation of living organisms from non-living substances. It sounds an unlikely thing to happen, but unless it was created from nothing at all, then this must be how life started on Earth. Unless it was brought here by aliens, in which case
abiogenesis must have occurred on whichever planet they came from.
Oh, and the spontaneous generation of living forms is also called
abiogenesis. Gosh, who'd have thought that explaining the creation of life would be complicated?
Here's a fluffy, baby living organism. If you don't know how babies are created, ask strangers on the bus. You'll be sure to get a seat to yourself.
