So if someone would have killed my zygote (fertilized egg), where would I be? Would I still be here?

I'll go one step further... what if the sperm on the night you were conceived were killed with spermicide? Would you be here? Nope. But sperm is not life. And neither is a zygote.

"what if the sperm on the night you were conceived were killed with spermicide? Would you be here? Nope."

Is Plan B a spemicide? Because what you say is true. If the sperm were rendered useless by a spermicide, then no conception would take place.
