You are human.
What is a human?
A human is an organization of energy defined by evolution.
— human
Here is a example demonstrating how evolution defines a human.
Suppose a human does not have sex
unless the human has a genetic trait,
which gives them sexual urges (to have sex).
Suppose a human ("child") is created when two humans ("parents") have sex.
Suppose a child inherits their parents' genetic traits.
---
You observe a generation of humans (e.g., "Gen X").
Some humans in this group
have genetic traits
which give them sexual urges
so these humans have sex (to create children in "Gen Z").
Some humans in this group
have a mutated genetic trait
which removes their sexual urges
so these humans don't have sex (and create 0 children in "Gen Z").
You observe the next generation of humans (e.g., Gen Z, who are children of Gen X).
99.9% of humans in this group, Gen Z,
have genetic traits from their parents
and
mutated genetic traits which do not affect their sexual urges
to have sex (to create humans in the next generation).
0.1% of humans in this group, Gen Z,
have genetic traits from their parents
and
mutated genetic traits which remove their sexual urges
so these humans don't have sex (and create 0 children in the next generation).

Suppose you observe "a human is an organization of energy which has a sexual urge" because 99.9% of humans are expected to have sexual urges (in any generation).
This observation distinguishes a human from "any other organization of energy" by defining a human as "an organization of energy with a sexual urge".
---
Suppose you observe other traits which distinguish a "human" from another "organization of energy".
The human is defined by these observed traits, which are developed by evolution.
How does a human behave?
A human acts on emotion to reproduce.
Here is an example demonstrating how a human acts in a tribe.
Here is an example demonstrating how a human acts in a megacity.
Suppose you cannot act on your emotion.
The world dominates you.
Here is an example of domination in the world.
Suppose there is a lion and a gazelle.
