How are eathworms created?
Question Date: 2011-09-03
Answer 1:

Even though they are born hermaphrodites, earthworms will still need another of their kind, to be able to mate. And so, after mating, then will they start excreting the eggs that they have produced

Worms come from cocoons (also known as egg cases), and these usually go through an incubation period of about 23 days before they start hatching.

Answer 2:

Earthworms are animals; they lay eggs that hatch into baby earthworms.
