Not sure...I think life is at conception...but as for a soul...I don't know at what point a baby would get a soul. I guess if I had to give an answer I would guess at conception as well.

But Futuremum I guess (I've said guess a lot here hey) that you would be right. Having a soul would make one an eternal being, so I don't think that a baby lost before birth would cease to exist, if it had a soul.
