Extract of sample "Building Life from Star-Stuff"

In Carl Sagan’s (Former famous American astronomer) opinion, everything we see around us has come from stars.

His argument was based on the fact that all the stars and our bodies have some common basic elements like hydrogen and helium. “Life on Earth was made possible by the death of stars. Atoms like carbon and oxygen were expelled in the last few dying gasps of stars after their final supplies of hydrogen fuel were used up” (Building Life from Star-Stuff) Hydrogen clouds were the fundamental element block of all the stars which then combine to form different elements as a result of the extremely hot conditions and other stellar reactions.

The reason for the immense energy liberation from stars is because of the combination of hydrogen atoms to form helium molecules (Nuclear fusion). We all know that we have life energy, but we don’t know the exact source of that energy.
