When you stop breathing you’re no longer a “living person”. Your cells are often alive for a while and there are some human cell lineages that have persisted for some time past the animal death. You are still biologically alive after its clear you’ve died as a person.
Even in the bible they don’t value a fetus like they do a person
There is ambiguity in the word “life” that doesnt translate well even among english speakers.
Suppose some “angel” did come down and try to communicate something to you and you wrote it down in english words today, do you think you’d be able to capture and tell people accurately what the angel intended or do you think its possible to maybe misquote a divine messager such that a bunch of dumbasses in a second language think a fetus is a person and use that interpretation as a test of faith that they mandate into law?
