It is alive, it is human DNA, so why is it not life?
Are you literate?
For it to qualify to be alive it has to have lungs to breath it would have to have the capability to breath air. It would need a brain for function and control of a body, it has to have a body, it has to have a heart to circulate blood, it has to actually have blood. I would need a liver to clean out the toxins. It would need food and water to stay alive. It would actually need to have a mouth, digestive system and a nose to actually eat and breathe.
A zygote doesn't have any of those things.
Human skin has DNA. Human fingernails have DNA. Human saliva and hair do too. Are you saying that whenever I comb my hair and hair come comes out that I"m killing a human life? Are you saying that every time I have my hair cut I'm killing human life? Are you saying that when I clip fingernails I'm killing human life? Are you saying that when I brush my teeth or eat acidic food I'm killing human life?
Really you need to come back to reality. Just having human DNA doesn't make it life. By any measure of science or law.
Are you educated?
