Most debates, especially "official" debates, are unwinnable by a liberal. Y'all simply take the opposite side of reality. You are a prime example of this- you think that the evidence that God exists isn't sufficient for you, when in reality you are simply stubborn and hard-hearted. This means that you start out in a state of wrongness that can never be overcome.
Even without factoring in that God creates each and every human, and it is stupid to not acknowledge this, every human being alive today, even you, started out life as a "fetus". You will never be able to come to a conclusion as to when a human being actually starts being a human being, and what an insane ideology in the first place.
A hunter is walking through the woods. He hears some rustling in the bushes up ahead, but he cannot see what is making the noise. Still, he has been tracking a deer for nearly 2 hours, and he does not want to lose his chance. He shoots into the bushes, and kills another hunter. Since he wasn't certain as to who or what was making those noises, he "probably" shouldn't have taken the shot until he was sure.
You have no idea when a human being becomes a human being, so to approve the murder of that unborn child is as morose and immoral as a person can be. The time for making a choice took place before the child was conceived. Your inability to grasp this is demonstrative of how corrupt your heart is- do you see this yet?
p.s. A human being is a human being at the moment of conception, something that was determined by God. He will by no means clear the guilty.
