Who said they are ?
You're implying it by going on and on about sperm and how they develop into a human being. Typical outdated nonsense. You haven't mentioned the female eggs or the womb once. We receive half of our genetic information from our mothers, of course.
Sperm cells are not anything special and I find it offensive that you're cutting the female completely out of reproduction. But I guess I'm expecting too much since you follow a religion that came into existence during a time of scientific ignorance and extreme sexism.
