Alien Base: The Evidence for Extraterrestrial Colonization of Earth: COSMOGONY
Janus expounded on cosmogony — the origin of life in the universe seemingly lending support to the so-called ‘Big Bang’ theory, which he referred to as ‘the generally accepted theory’ of an expanding universe that ‘originated from the giant explosion of a vast area of high density gas which contained all the elements necessary for life and matter’. ‘If you accept this theory,’ he went on, ‘then all galaxies contain the elements necessary for life and matter; even at the very boundaries of the expansion, the original explosion is still distributing these elements .
If you accept the theory of the expanding universe you accept that it is an ocean of galaxies with solar and planetary systems similar to our own. By the laws of probability there must be millions of planets in the universe supporting life, and within our own galaxy thousands supporting life more advanced than on Earth.’
Earth is a young planet with its Sun a young mother. We may hazard a guess that other planets in [this] solar system are unlikely to support life except in possibly rudimentary cellular form and are no more than uninhabited and hostile islands. But imagine a galactic solar system somewhere in space with conditions similar to Earth except that its Sun is in the autumn of its life.
Provided its inhabitants have survived wars and alien invasion, it is impossible to imagine what super-technology and cultural advancement they have reached . . .
