If you don't think a 'fetus' is never aware of its surroundings and where it is, you are wrong. How would you explain a baby responding to a mother's voice or sounds from within the womb?
I believe this is where the new resurgence for pro life is coming from. Because modern science is showing us it is not a 'fetus' for as long as we thought and said fetus starts to feel pain and become aware. Just because we don't remember it when growing up doesn't make it not true. What of anything from your first years do you remember? Obviously you don't mean anyone up to 2 years old or more should be indiscriminately killed just because when they get older they won't remember what their surroundings were.
