#so why Infertile netherworld god so popular when there are more counter evidence

I really like how Olympiodorus, same as Euripides, offhandedly mentions children of Hades, like it's some kind of common thing.

Hence too they say that some are sons of Zeus, some of Poseidon and some of Pluto, in accordance with the allocation of each of the three. For someone with a divine and heavenly character we call a son of Zeus, someone with an earthly character we call a son of Pluto and someone with an intermediate character we call a son of Poseidon. (Olympiodorus, Commentary On Plato’s Gorgias,47.5)
