While Helium is the second most abundant Element in the universe, I believe the author was speaking of things more complex that single element molecules.
BTW, the physical and chemical properties of water and its abundance are some of the strongest proofs of the Creator God, at least for anyone who has some knowledge of chemistry, physics, logic and probability.
And a smidgen of intellectual honesty!
“While Helium is the second most abundant Element in the universe, I believe the author was speaking of things more complex that single element molecules.”
I realize that and if he had said “molecule” I would not have disputed it, however he specifically said substance.
