Not all stars were born at the same time. The first stars formed after the Big Bang were composed mainly of hydrogen and helium. Life did not exist around these star systems. These (population 3) stars were massive and had short lives. When these stars died by supernova, they produced heavier elements and ejected them into space. As newer stars formed (population 2), they formed not only of hydrogen and helium, but of heavier elements as their nebula passed through the debris of the older stars. In fact, it may have helped cause the nebula to coallesce. The nebula that came to form our Sun (population 1) passed through not only population 3 debris but perhaps also some population 2 debris thus not just composed of hydrogen and helium but also of some of the heavier elements. Without these heavier elements, life would not be possible.
mark- maybe you should print up a religious response that you can put onto all astronomy questions in the same way that you post your carbon copy response to all alien/UFO questions.

Not all star formation is induced by supernovae. In any case, the relative velocity between the proto-solarsystem cloud and a nearby supernova would typically be about 10 kilometers per second. Over the 4.7 billion years that have passed since the formation of the solar system, any remnant with that much relative velocity would have moved about 150,000 lightyears away --- far enough to put it anywhere in the Milky Way, even on the other side. We'll never find it.

You're quite right, but our sun wasn't the supernova. The heavy elements were formed in previous generations of stars.
When massive stars explode as supernovas, they create heavy elements (iron, nickel, and heavier ones) in that explosion and expel those elements out into interstellar space. The clouds of dust and gas (and those heavy elements) start to collapse (often due to the shock waves of that same and other supernova) into the next generation of stars.
Our sun is theorized to be a third-generation star, formed after 2 "waves" of supernovas enriched the gas and dust in space with heavier elements.
Its those heavier elements that became the rocks of the planets in our system.

Yes, all the heavier elements like iron, gold, uranium, etc., could only have been produced in the intense temperature and pressure of an ancient supernova(s). Most of the elements in your own body were created that way. As Carl Sagan liked to say, "We're all made of star stuff."

All of the elements came from inside dead stars. Everything originated from hydrogen and it takes the tremendous heat inside stars to fuse atoms together to create the other elements.

it was... we have a lot of heavy elements on the earth including Uranium. these could only have been formed in a dying star. we are second maybe third or fourth generation. some of the heavier stars live brief (millions of years) lives.

The material in the earth and other planets was formed in the deaths of other stars.

Yes, some people think that is true. And after lots of study I think that they might be correct.
