Stars (our parents)
On dying they form atoms that become parts of other nebula that form other stars forming galaxies.
Great explosions cause light and heat called supernova
When dying they explode forming complicated elements of life
Nuclear reactions happemimg inside forming light and heat energy
Have a definite lifecycle
