Someone confronted me with the question if we evolved then who evolved first the male or female and how this worked why do we have male and female? Can someone please explain. I really wanna show this ex-youth pastor of mine that with some study I can prove to him that evolution is a fact. It may be a theory but a theory explaining a fact. thanks and peace.
