Hydrogen is approximately 10 times less dense than natural gas. Simply, there is less hydrogen in a given volume than there would be natural gas.
I don't know whether this is so, but it may well be. This is related to the low density of hydrogen. A kilogram of hydrogen takes up much more space than a kilogram of natural gas.
Not invented. Natural element, been around as long as the universe has existed.
Since density is mass / volume, the natural SI unit is kilogram / cubic meter.
Making sense.
Fusion experiments and designs for fusion reactors generally focus on hydrogen, in the forms of deuterium (hydrogen-2) and/or tritium (hydrogen-3). It should be born in mind that there is not much preventing any atom of any natural element undergoing fusion with something else. In fact, virtually all of what is around us is either hydrogen or something made by fusion, and this includes all the heavy elements like lead uranium.

No, since there is little or no free hydrogen on Earth. (plenty in the sun, and it is a natural resource there.) There is bound hydrogen on Earth (mostly water), but the energy required to extract it is greater than the energy it gives up in burning.
the natural world behaves in a consistent and predictable manner :)

Hydrogen is one of the most abundant gasses it is natural
Hydrogen is explosive!!!! What about the earth's atmosphere? That is about 80% nitrogen.
