“So the 22 week old *object* that is delivered and put in NICU is what then? Is it a baby? Is it a *fetus*? Is it human or not?”
22-week preemies surviving outside the womb are exceedingly rare, even with modern medical technology. I did see a story about a 21-week preemie who survived for a year, albeit after experiencing severe problems. It was a black baby. Apparently, black preemies have a much better chance of survival than white preemies...something I find interesting..blacks develop faster in the womb, apparently. Although we make medical laws based on the average and not the 1 in a million miracle, I would not object to immediately moving the cutoff back to 18-20 weeks and perhaps further as medical science progresses. Of course, this leads us down the path of eventually reaching the point where a human mother’s womb is no longer necessary. We’ll be able to grow fetuses in artificial wombs...cloning...eugenics...made-to-order babies...The Island. That’s a whole ‘nother can of worms right there...
Will your unscientific definition of human life change when medical technology changes and the unborn child can survive outside of the womb at 20 weeks? Then 16 weeks? Etc.? The fact of the matter is that the scientific definition of human life demonstrates that an unborn child is a human life shortly after conception. You're the one who claimed to use the scientific definition - now use it.
