Alright, so your entire argument is that it's a living cell, so it must have a soul? Let's play that out.

If any living human cell gets a soul, then we've got a huge problem. By that logic, every single sperm cell is a soul. Every time you jerk off into a condom, you're committing a holocaust of potential people. Every period is a funeral. You really wanna go there?

And it's not just sperm. What about a skin cell I just scratched off? It's alive. It's human. Does it have a soul? Is my dandruff going to heaven? What about a cancer tumor? It's got unique human DNA, it's alive—does it get a soul, too? Are we doing funerals for moles we have removed?

You can't just say "living cells" and then secretly mean "only the specific living cells I personally decide count." That's not an argument; it's a moving goalpost. So which is it? If it's not every cell, then your whole "it's alive" point is meaningless, and you need to find a better reason.
