or may be a fish and a bird?
Just like what most Christians believed... spirit people with real humans???
that's how Jesus came forth right? Mary and the spirit being had something together and walla.. she conceived!

if it is impossible for a dog and a cat or fish and bird to reproduce new species then it is also impossible for real human and spirit beings to breed,yes????

no seriously, educate me here, tell me what I don't or can't see.. make me see what you can see... peace!
