    So that eased off after the various littermate stars drifted apart.

    It has been postulated that the planet Jupiter started that way long
    before there was life on Earth.

    Lately I have read headlines that assume that Sol had 6,000 equivalent stars
    in a nursery across the Galaxy and from which it was ejected to move to the peripheral arm of the Galaxy. But on Earth we had a terrific impact
    before complex
    life evolved that tore the Moon out of the crust of the Earth. Life may
    have
    already existed in the Universe even before the Earth was conglomerated.
    We know that the early Sol system was heated by an isotope of Aluminium which could have only come from an exploding previous star. The core of the Earth could have come from one or more supernova. The Iron of the Core is
    one of the reasons we have atmosphere and that live is not scoured from
    the surface of the Earth by solar radiation.
