Yes; helium appear from radioactive disintegration of uranium or thorium.
hmmmmmm............not found on EARTH( may be found in the core of the SUN).......but can be prepared on earth. Solid helium requires a temperature of 1-1.5 K (about −272 °C or −457 °F) and about 25 bar (2.5 MPa) of pressure.
No. Helium is a gas and is generally found in the earth's atmosphere.

Helium is a gas and is found either in the earth's atmosphere or in the core of the sun.
Helium is found in the sun. It is also found in the Earth's atmosphere.

helium is a noble gas and is found in the earth's atmosphere and not in the oceans nor in the earth's crust
Through the spectrum. Signatures of an element was found that was not known on Earth. Some years later, it was also found on Earth. Hence the name, "helium".Through the spectrum.

Helium gas is found on Earth trapped under ground in the rocks and it is also found in the Sun.
Helium is found in the sun or stars. It is also found in the Earth's atmosphere. +++ And underground: a stable product of the natural radioactive decay of uranium, and extracted commercially from natural-gas. That in the atmosphere may well have been released by volcanoes.
Helium makes up about 0.0005% of the earth's atmosphere.
