I used to be a zygote
A small little thing
Which known as cell

I used to be a zygote
Living in the host body
Which I never knew before

I used to be a zygote
Having a lot of friends
And yet to dissapear
In a blink of an eye

I used to be a zygote
And when I was an adolescence
I called myself
Embryo

I used to be a zygote
As I grew older
I changed my identity
With the one called
Fetus
