I go by development and cognitive ability.

Teens can work. 5 year old can't.

Teens have higher medical freedoms. A 2 year old doesn't.

Simply because "they're a child" is vague and ignores different aspects.

Here in Canada. Once you're 16. You're capable of making your own medical decisions without parent interference.

Probably 2 males agruing about pregnancy like it will affect them at all in their life time.

Zygote first stage
Embryo second stage

Human is a classification of species

Human being is a term for sentient being.

" is and was and is human, therefore a person with rights, only human, and nothing else, but. The distinction of in- and ex-vitro has no medical/scientific distinction; only one by flawed law."

Very biological incorrect.

When a fertilized egg happens. It doesn't automatically make fully form fetus. It's a process of 40-42 gestation to complete this process. Newborn is a formed person. A 6 week Embryo is not a fully formed human.

Also, human is a classification of species.

Human being is term to discrib a person or "sentient being".

For fetuses to have ability of or to be a person or to be a being. They have to have ability of perception/experience.
