What does science say how the Earth was created?

Our Sun is considered a second generation star born from a supernova. Contained in the supernova, are heavy elements such iron. The iron decayed to become rock boulders. The Earth was formed by numerous collisions of boulders, rocks, and dust. Later, it would be comets and asteroids. In Skylab, America's first space station (May 1973-Feb 1974), there was an experiment to see how particles free of gravity would react. Those particles became attracted to one another which proves that in the vacuum of space, objects with mass, will attract one another.
