A fetus needs a womb to develop, and for the process of birth to occur. These two things are steps which cannot be skipped if one wishes to deem its potential future to be “like ours”. Which is quite a bit beyond what any already-developed-and-born child or adult needs. The stages of a fetus from blastocyst to zygote to birth are all of equal importance or the fetus will NOT become a child. Given this fact, I’m left wondering why the point of conception is where you’ve decided the beginnings of morality ought to be considered. I would say the end stages of the birth process (it is unimportant whether the means are natural or artificial, “birth” being a medical term which encompasses many methods, none of which are any less required for a child to have “a future like ours” than the moment sperm and ovum join) is where the beginning of morality ought to be placed. But then, we’d have to factor in the role of a host/womb/birther, which seems to be a task ill-suited to the men of this discussion.
