The point isn’t that is is virtually impossible, it is literally impossible. Everything, every single thing in the Universe, is chemicals. Most of which have scary sounding and hard to pronounce names. Dihydrogen monoxide, for example, is water. Plain, simple water. But if you picked up something off the shelf and its ingredient list said “dihydrogen monoxide” instead of “water” you’d probably put it back. If you saw a list of the natural chemical breakdown of your blood your head would probably spin.
The whole world is chemicals. But just because you can’t pronounce or don’t understand the chemical name for something doesn’t make it inherently bad.
