That's not what a human is. These things have names, zygotes, embryos, fetus. None of these are living humans yet. They're pre humans. collection of cells without an identity or awareness. Simplest of brain function where they might only respond to stimulus.

The difference between fetus and infants is the first is still attached to its mother. Its continued growth depends on its attachment to mother. Similar to a tumor.

I don't think you actually understand what you are talking about if you are confused about the term viability https://en.wikipedia.org/wiki/Fetal_viability

Your link to photos means you are forming your opinion based off emotion and not understanding the difference between cells splitting, and what a independent human is.

At what point do you think the sperm and egg are human? Even the first split after they join is still just two cells.

What proof do you have that says a fetus at 16 weeks is alive? How are you defining alive?

> it has all its organs. It just needs to grow.

This is still dependent on the mother, it is not its own thing at this point.
