“Although it might seem a bit ludicrous today, for thousands of years it was believed that life regularly arose from the elements without first being formed through a seed, egg, or other traditional means of reproduction.”
Uh, this one is still going strong today, only now it’s called the THEORY of Darwinian Evolution, and “mud-puddle” has been changed to “seawater puddle bombarded by cosmic rays” and the time frame for “spontaneity” has been extended a bit.
Oh, and it’s still just as ludicrous.
