Besides, it doesn’t “all” originate from Earth. If you want to be really uselessly pedantic, nothing on Earth originated on Earth.

No, not everything. Atoms, subatomic particles, light, electromagnetism, etc. are not chemicals. There are many things we experience in everyday life that are not chemicals.

With the exception of protons, isolated subatomic particle in general aren't chemicals.
I ended up on the jury, so apparently this performance successfully masked my pro-defense bias.

Light isn't chemicals. Sound isn't chemicals, it's the vibration of chemicals. The billions of neutrinos passing through you right now aren't chemicals. Etc. All the matter we interact with in everyday life is chemicals, but lots of things aren't chemicals.
Things that aren't naturally occurring would be supernatural, no?
