Helium (aka balloon air that makes them float up) is a special type of gas that gives young people squeaky voices, but does not affect the brain, which would cause them to mis-understand most things. It can sometimes be hard to burst a balloon with helium in it. I wish they made them with extra helium so 200 balloons could lift an adult.
It is possible that Helium could have evolved from many, many things..
So as you can see, Helium is an advanced yet low-numbered gas but is often considered the root of gases.
