You obviously haven't read a bible to any depth.
God talks about "nations" being in the womb of Rebekah. He opened/close the womb of Rachel and of others in scripture.
Samson was a Nazerite "from the womb".
Job says that God "made him" in his "mother's womb".
I could go on and on. Please read up on this some more, your argument is very ignorant of what scripture actually says about this.
God is omniscient though, so I don’t think that’s a useful standard for the cops to use when deciding who to throw in jail.
So at least at some distance after conception, yes, medical science supports seeing a fetus as a human, with life of its own.
It says no such thing. It says that Adam's life began upon first breath. Adam was also created as a full grown man, so it's clearly not an example for human life as a whole. The Bible doesn’t teach that every man comes to life at first breath any more than it teaches that every woman comes from the rib of a man (from https://www.str.org/w/does-bible-teach-life-begins-first-bre...)
The Bible does say, in multiple places, clearly imply that life begins in the womb. For example, when John leaped for joy in his mother's womb, announcing the coming of the Lord.
“Science”(whatever that means) doesn’t really weigh in on what “personhood” is.
There’s also no indication that people even used to think that life began in utero, and that anything less than a fully formed infant was alive and capable of surviving.
