Yes, they are human cells, but they are far from being a full blown human; they still lack brains. They will also not survive without the mother.
Years ago, a baby born just a few weeks premature had a slim chance for survival. Now , babies born at 6 months can and do survive.
So as medical technology pushes that date back further, will the unborn suddenly 'become human' at an earlier date?
The unborn has a brain and can now survive outside the mother at a much earlier date than before. Why do you still support abortion on demand up to the point of birth, CI? (If you don't, then at EXACTLY what point in gestation do you think abortion should be illegal?)
If fertilization occurs in the lab and the unborn is never implanted into the mother, but allowed to grow for all nine months without being in the womb (not a possibility now, but can be in the future) will this one be human from the moment of fertilization because it can survive without the mother?
Are all of the embryos in the lab today truly 'living human beings' because they are surviving NOW without the mother?
You see how flimsy the criteria you've set up as disqualifying the unborn are, CI?
So, from a medical standpoint at what point EXACTLY does the unborn become a living human being, CI?
