Are plants alive? Jelly fish? Flatworms? Single celled bacteria? Amoebas? Protozoa? They have no blood. By your "reasoning" (for lack of a better term) they aren't alive.
Already answered. But maybe you need to do a bit of research on that to see for yourself.
Day 21, Week 3: The heart begins to beat.
Day 28, Week 4: The backbone and muscles are forming. Arms, legs, eyes and ears have begun to show. Hair has begun to sprout.
Day 30: The embryo is 10,000 times larger than the original fertilized egg. The heart is pumping increasing quantities of blood through the circulatory system.
Hmmm. The heart is beating at day 21. If it's beating, it's pumping blood. The fetus is already formed with bodily parts that require blood to function. By day 30, the heart is pumping increasing quantities of blood.
The crux of his misinformation: Leviticus directly says that the life of the flesh is in the blood. There is no blood at conception, so how can life begin at conception? At least Biblically speaking?. Well, if I take this literally (though it has nothing to do with our topic at hand), I'd say life of the flesh is already developed as early as day 21 if not before. Oh, well, another idiotic argument destroyed. Man, how people set themselves up...
