Why hydrogen and helium aren't considered dark matter and dark energy

[noblegas]

matter in The universe is thought to be made up of 75 percent hydrogen and helium is thought to make up 25 percent of helium; Dark matter is thought to make up 25 percent of the universe and 75 percent dark energy; that's an interesting coincidence. , and currently physicists are not certain about what the elemental constituents of dark energy, and dark matter are. Why haven't the elements hydrogen and helium been suggested as the main candidates for dark energy and dark matter?

More importantly - the Earth's surface is thought to be 75% water and 25% land. Why haven't Earth and water been suggested as the main candidates for dark matter and dark energy? Or for that matter, doesn't that mean that land is really made out of helium?

This is why scientists don't concern themselves with numerological nonsense.

Not to mention that neither of those have characteristics that they should have - Dark matter doesn't interact with light, while Hydrogen and Helium do. Dark energy has negative pressure, while Hydrogen and Helium don't.

Land and water are not fundamental elements of nature that make up most of the existing matter in theuniverse, while hydrogen and helium are . Most matter is made of hydrogen and hellium, why is it none-sense to hypothesize that dark energy and dark matter is made of hydrogen and helium respectively? Hydrogen and helium don't all come n the same physical form because you have the hydrogen isotopes deuterium and tritium and they don't share the same physical property. Perhaps there is a hydrogen isotope that doesn't interact with light out their scientists have not yet discovered that could be the leading candidate that makes of the composition of this dark energy. Quintessence , the leading candidate for the composition of dark energy have yet to be physically observed , and it is not well defined. Some physics theories proposed that dark matter could be baryonic and all normal matter is baryonic
