I've been researching what scientists have to say about when life starts, and I can't find a clear answer.  Is it at conception, when the heart starts beating, when it stops being a parasite to it's host, when?

For personhood, one might consider whenever the human brain becomes active. Still quite a fuzzy line.

If you are talking about the moment when a new life form starts I would say it's when the egg get fertilized and the cells between to split.  However, if you are talking about when the embryo becomes a "being" in the sense of thoughts, then I would agree with Caeser that brain waves would be an indicator of some sort of consciousness. I think Brain waves are detected around 6 weeks.

One can also consider how we project the idea of life based on our own feelings. For instance, a woman with an unwanted pregnancy may not consider the developing zygote or fetus a life, and a woman with a wanted pregnancy may consider it a life the second she finds she's pregnant.
