The noble gases are rather uncommon on Earth. Collectively, they make up about 1 percent of Earth's atmosphere. Most of the noble gases have been detected in small amounts in minerals found in Earth's crust and in meteorites. They are thought to have been released into the atmosphere long ago as by-products of the decay of radioactive elements in Earth's crust. (Radioactivity is the property that some elements have of spontaneously giving off energy in the form of particles or waves when their nuclei disintegrate.)
Noble gases are mostly sourced from the fractional distillation of air, where they are separated from other gases like nitrogen and oxygen. Helium is also extracted from natural gas deposits. Trace amounts of noble gases are found in minerals and radioactive decay processes.
Noble gasses are obtained by compressing air into a liquid, then distilling it into a fractional column, very similar to how crude oil is turned into tar, diesel, petrol, jet fuel, gas, etc.
out of the still you selectively separate the different gasses that are in the atmosphere by controlling the temperature and pressure at the top of the still.

they are found as gases in the atmosphere (along with other gases)
