Thanks for the links (no colin) dont worry bout it lol
It is less of a theory and more of an observation as far as the nature of earth is concern if you ask me. For example, we don't know WHY gravity works or how but we can observe it's effects and talk intelligently on that. To explain the questions you ask would require more theory and diggin (literally)
My theory on that though is that the earth is not a closed isolated system rather it is along with all of the planets on this level of understanding part of a larger system, which the sun's energy when coinciding with certaind orbits depending on it's stage of star life 'activate' certain planets. Making it possible for ecosystems and life. So in another few billion years saturn may be in the same 'life zone" as the Earth is now. Also several prehistoric planets may have already been consumed by the sun.
(I am actually paralleling a lot of this into my blog which I can share with you when I finish it may make some youtube vids as well, if I ever get along to it)
i agree wit this
i think that the idea that our planet is separate from anything is more of a western idea
but even still i have to agree that the planets are all linked by way of the sun
and the life cycles on the planets in the solar system are determined by the life cycle of the sun
where our star goes we follow
