Everything in the universe; that is, all things made of matter, are composed of chemical elements.
These elements react with each other in a way that is constant and predictable according to the laws of physics.
Furthermore, all of these elements have been reacting with each other since their inception during the big bang.
All chemicals; from those in coal, water, eye tissue, fire, thought, emotion, consciousness, all of it is just part of a massive chemical chain reaction that has been going on since the dawn of physical existence and will continue until is theoretical end.
Everything that has ever happened to you, that will ever happen to you, is just part of a massive chemical avalanche that we only believe we have control over because we are unable to see the entirety of the system, only our part in it.
Somebody refute me before the world starts to disappear.
