does it have any uses?
Yes, commercial, recreational, scientific as well as medical use.
Helium
The use of helium reduces the distorting effects of temperature variations in the space between lenses in some telescopes, due to its extremely low index of refraction. 
where does the world's helium come from Most helium on Earth is a result of radioactive decay and is found in large amounts in minerals of uranium and thorium, including uraninite. how is it extracted? UNANSWERABLE

Helium [SEP] Scientific uses
The use of helium reduces the distorting effects of temperature variations in the space between lenses in some telescopes, due to its extremely low index of refraction. This method is especially used in solar telescopes where a vacuum tight telescope tube would be too heavy. Helium is a commonly used carrier gas for gas chromatography. The age of rocks and minerals that contain uranium and thorium can be estimated by measuring the level of helium with a process known as helium dating.
