I was listening to 2 people having a debate on abortion, and one person asked the other "when does life begin" and the other person said when it comes to humans it doesn't begin, you have an alive sperm and an alive egg coming together to make an alive human; at no point is anything dead coming to life, they just go from one form of life to another. I'm no biologist, but this make sense to me, yet I hear people claiming life begins at conception; am I missing something here?
