It is said that when sun dies from hydrogen to iron elements are formed and when busted spread in space .the other elements are formed by chemical reaction by these elements
They're not formed here. They were formed in stars - mainly as they exploded.
Elements are not produced in the Earth's atmosphere because they are formed through nuclear fusion processes in stars or supernovae. The elements found on Earth were created during these events and then dispersed into the universe, eventually coalescing to form celestial bodies like planets.
Elements that occur naturally on Earth are called "native elements." These elements are found in their pure form without being combined with other elements. Some examples include gold, silver, and diamond.
Carbon is a chemical substance found in the Earth but not formed by plants or animals.
Total 108 elements are found in earth till 2007 dec 56 to 72 elements are in the human body, 22 to 36 are in the animal body 18 22 elements in birds are found
The materials that formed the Earth are in fact OLDER than the Earth, because they were around BEFORE the Earth was formed. The Elements that you are made of were formed inside STARS before the Earth ever existed.
Helium is found in the sun. It is also found in the Earth's atmosphere.
Such elements are formed within stars. The heavy elements which are currently here on Earth were formed in stars some time ago, and then they were blown into space in supernova explosions.

Oxygen
In the rocks and minerals that make up the Earth.
