Hydrogen and Oxygen have the wrong names
Hydrogen means “produces water,” which is fine in and of itself, hydrogen being the H in H2O, but the word Oxygen means “produces acid,” because its discoverer mistakenly believed it to be the basis of all acids. In reality, hydrogen is the basis of all acids, also being the H in pH.
Our bodies take in sugar and oxygen, and excrete carbon dioxide and water. We don’t metabolize hydrogen by itself, only when it is locked into carbohydrates like glucose, but we do metabolize oxygen gas to produce water.
Oxygen should be called hydrogen, and hydrogen should be called either oxygen, OR helium. Helium literally means “of the sun,” but only comprises 24.85% of its mass, compared to hydrogen’s 73.46%. Hydrogen is more “of the sun” than helium is.
