Carbon Creation
One day, after millions of years, the hydrogen fuel in a stellar core will get exhausted, by its conversion into helium. Then, the star, which has till then maintained a hydrostatic equilibrium, by balancing thermal pressure generated through fusion, against the crunch of gravity, gives in again to gravitational collapse.
The core starts heating up again until it reaches a temperature, where three helium nuclei start fusing into carbon. In this process, carbon, the element on which all of our organic life is based, is created. Through a separate pathway, some oxygen is also created through helium fusion. Thus, two of the life-supporting elements on Earth are created through fusion.
That Carbon?

And who created the hydrogen fuel?
We can play all day...
