Even you meta, and I am honestly disappointed that the only rebuttal is "Well sperm is alive too!". Weak!
I'm sorry to disappoint.
I wasn't going to tackle the the whole problem of when the soul enters the body. That's just too messy, so I figured I'd instead point out the obvious: sperm cells, egg cells, stem cells, etc. are not human beings. Neither are skin cells, heart muscle cells, or lung cells. Those aren't humans, either. As it turns out mitochondria are definitely not human, and in fact, much of the human body is itself not human, either.
Similarly, a potential human isn't a human. As I pointed out earlier, women who have periods which contain fertilized eggs are not having an abortion. Neither is harvesting stem cells for scientific research. If we suppose that a potential human is a human, than I should be in jail for years of protected sex. Really, I should have got charged with at least manslaughter when I was 14 for dumping my 13 year old girlfriend. I would perpetually exist in a morally grey state, as I tend to spend a lot of my days doing things other than actively getting women pregnant. The number of potential babies I've singlehandedly prevented the birth of is mind blowing.
A human being is an incredibly complicated multicellular organism / ecosystem / ideal. They aren't a cell or even a small collection of cells, nor are they a potentiality. On the other hand, I
am a human being.
My life matters.
Your life matters. Let's not make this any more confusing than it needs to be. It's already confusing enough as it is, because there's no hard and fast line between "human" and "not human".
One of the central concerns I pointed out at the very beginning is the problem of what it means to be human. If this has all the quantification of being human:
Then I must be something more than human, because I'm capable of so much more. I can hear, see, feel, taste, touch, smell, think, talk, eat, poop, run, swim, jump, make posts on indie gaming forums, and even make new humans with the help of another!
The zygote above? It just sort of sits there, and if external conditions permit, it might be form, one day, into a human being as well. But not left on its own. There's nothing about this little bundle of cells that is anything like any humans I know of. To argue that its a human just because its one of the required components to make a human is absurd.

An egg cell on its own will never begin the process for human life.
Neither will that zygote. That zygote requires an
entire human to manufacture a human being. It's not like it magically materializes a baby out of itself, growing organs from organelles, limbs out of cytoplasm, and a brain from one of its nuclei. All these things still have to come from somewhere else; the mother.
