Are babies alive upon conception?
YES!!!! Fully alive, fully human. A body soul unity, endowed by God with all the rights given to you or I. To quote Dr. Seuss : “A person's a person, no matter how small.”
yes and no
depends on how you look at it
At the point of conception they are a single fertilized cell, that is alive.
The fetus is, there is no baby.
well they are one cell that is alive which is called a zygote (i think) which is alive but it is not a human as it has not yet even become a foetus
Technically, Yes. But it is not the conscious, breathing sort of alive. The fetus is alive, but it is not a baby, yet.
As many answers as there are people. I don't believe anyone can define "life" as regards conception.
