With the invention of the telescope and the further development of technology we've gotten a more and more detailed picture of the world. We've learned about the birth of stars and star death. Stars provide the essential light for life. We discovered that almost every chemical element in our body was formed inside the stars. The formation of our solar system is also caused by previously lived stars. Our galaxy formation is the result of a supernova shock wave. Our existence is a natural consequence of the existence of the stars.
