I'm unsure if you're joking, so I'll bite: if 6 is true (a fetus is a human), then is a zygote a human? Can a human be a single cell? Of course not.
btw it is sorted in a list not because of any argumentation structure.
i don't think (and don't see what indicated it to you) that there are only these 2 options in terms of worship targets. but phrasing the other option the "only" "right" one, paints me an intolerant blind-faithed, which i reject.
Btw, you might find https://en.wikipedia.org/wiki/Islam_and_abortion and https://en.wikipedia.org/wiki/Judaism_and_abortion interesting.
My understanding is that opinion polls show most people have a moderate opinion on abortion, which seems pretty reasonable given that "becoming human" is something that happens in a continuous manner over a 9-month period.
A cell being of a species does not make it an instance of that species, in the same way that a skin cell is a human cell but is not itself a human.
> "Can a human be a single cell?" can it be 2? or 3? …
If a single cell is not an instance of a human, it follows that there is some point during pregnancy where an instance of a human exists where one did not previously. Mostly the disagreement is about where this line is.
IMO, there is a substantial difference between a conceived egg and any other cells: an egg turns into a human being over time (provided it's left doing its businnes normally), other kind of cells don't operate this way AFAIK.
> there is some point during pregnancy where an instance of a human exists where one did not previously
completely agree. IMO we can even extend it by omitting the "If a single cell is not an instance of a human" condition: even if we qualify a specific single cell to be a human, there must be a point when it became a human.
why we usually threat neglecting the born and unborn differently? because they need different level and kind of care: eg. smoking hurts unborn differently than born. did the mother eat honey which happened to be infected and caused her embryo to die? it was not considered neglect until this honey-effect was discovered.
