Mafoo, while I understand your position, I don't agree with it. Most of the more religious people would tend to think that life begins at conception. I might go so far as to say that it begins before conception,
Jeremiah 1:4-5
4 The word of the LORD came to me, saying,
5 "Before I formed you in the womb I knew you,
before you were born I set you apart;
I appointed you as a prophet to the nations."
So... logically based on that, every life is planned and formed by God. If he "knows" you before hand, then at what point do you become a human? The only answer can be conception. This is from a Christian perspective.
