Our universe was born, some 14 billion years ago. Within that universe large amounts of elements, dust and gas mixed together and formed stars. When their inner fuel ran out, they, just like all other things, die. As they die they expel all of their matter. They explode. All of those elements mixed, and formed new elements and were now free in space to once again pull together forming a new star. Exploding. Releasing new compounds. Forming new stars. A space recycle system. Through those many recycled stars, eventually our galaxy was created. Our sun. Our solar system. Our earth. Our lives. If you trace our origins farther than our ancestors, farther than the earth and farther, you will find that we all are just star stuff.
