Yes technically everything on this planet is natural including the creations of man. Unfortunately this is not a particularly useful definition of the word. When we talk about natural what we mean is the systems of the planet that have been around a lot longer than the tiny slice of time since civilization emerged. Things that evolved rather than things that were conceived. Things there due to instinct rather than rational thought and planning. Words exist to draw boundaries, something cannot exist without its opposite. If everything is natural then what is unnatural? If your answer is nothing then you have discovered non duality which is fascinating but has no practical value. The practical value of defining what is natural is to understand our impact on the world and what that means for the future of the planet.
