Do you believe life begins at conception?

[Landslide Lyndon]

I don't mean to offend anybody, but whoever answers that question with a definite Yes or a definite No is just blowing smoke.

This isn't just a scientific question, this is a spiritual question. There will never be hard proof that validates one opinion or the other.
Of course the assertion that we should consider that life begins with the first signs of brain activity sounds logical. But even that is just a theory that is difficult to be validated since many people have a different perception of what constitues "life".
