What is the scientific basis behind the idea that humans are made out of stars?

The scientific basis behind the idea that humans are made out of stars is that the elements that make up our bodies, such as carbon, oxygen, and nitrogen, were created in the cores of stars through nuclear fusion. When these stars exploded in supernova events, these elements were scattered into space and eventually formed new stars, planets, and life forms, including humans. This connection between the elements in our bodies and the processes that occur in stars is what leads to the poetic notion that we are made of stardust.
