We understand that "nature" is a term that encompasses everything that has been created naturally on our planet, including animals, plants, climate, water, atmosphere, and geology that are not made by people.

I once discussed this very thing with a friend and I realized something curious.
Why is the human being not classified as something natural if it can be considered an animal? Because as far as we know, the human being has been created naturally on this planet. Although the term is used for everything that has not been created by man, technically that includes man himself.

Also, continuing with that same theme, why is everything that is created by human science called “Artificial”?
It is supposed to refer to something that cannot be conceived in nature without human intervention, but if we consider human itself as one outside of nature, then all creation could be considered natural.

For example:
Fire occurs naturally when different elements coincide to generate spontaneous combustion.

If we eliminate the factor “Coincidence” from the equation, we would have as a result the inventive nature of the human being.
