At the point of conception, a new human being exists. Whether you accept the concept of the human soul or not is irrelevant. From the point of conception, short of genetic abnormality, accidental death or abortion, the unique person will grow into nothing other than a fully formed human being. There are stages in all forms of life. But they all begin somewhere. Humans begin at conception.
I thought about returning hurtful comments in response to your nasty attacks on my beliefs, but I'd rather try to help you understand some simple truths about life, death and murder as it relates to this issue.
I sense much anger in you.
