Our origins are intertwined with the stars that formed billions of years ago from "summary" of The Cosmic Connection by Carl Sagan

It is a remarkable fact that the atoms of our bodies are traceable to the stars that manufactured them in their crucibles long ago. These stars, many of them billions of years older than our sun, went through their life cycles, burning hydrogen and helium, synthesizing heavier elements in their cores, and eventually exploding in spectacular supernova events that scattered these new elements across the cosmos. The iron in our blood, the calcium in our bones, the carbon in our cells - all of these were forged in the nuclear furnaces of ancient stars. As the debris from these stellar explosions mingled with other interstellar material, new stars and planets began to form, including our own solar system. We are truly made of stardust, products of a vast cosmic evolution that spans billions of years. This connection between ourselves and the stars underscores our place in the universe, our shared history with the cosmos. It is a humbling realization, reminding us of our smallness in the grand scheme of things yet also highlighting the interconnectedness of all life and matter in the universe. As we gaze up at the night sky, we are not just observers of distant celestial bodies but participants in a cosmic drama that has been unfolding since the beginning of time. Our origins are intertwined with those of the stars that illuminated the night sky long before our planet even existed, and our destinies are linked to the fate of the universe itself. It is a profound and awe-inspiring realization, one that invites us to contemplate our place in the vast expanse of space and time.
