Aliens from "outer space".......do you believe?

[Bowyn Aerrow]

The size of the universe, the abundance of stars, and now the abundance of confirmed planets around stars even planets of the correct size within the Goldilocks Zone of a star leave little room for doubt that life isn't going to happen all over the place.

The only thing that may be needed for life to exist long enough for technology using intelligence to arise is a large moon for the planet.

Earth has a really, really ginormous moon. Venus has no moon and look what she is like, all but totally tide locked to the sun with sweltering temperatures and acidic clouds. Mars, smaller with two minor moons is a bit more hospitable, and all signs are pointing that at one time, long long ago some sort of life may have existed. Methinks if Mars had a moon 1/3rd its size that whole internal cooling would have been stalled, thus the liquid metal core would still be spinning fast enough to generate a protective magnetic shield from radiation and Mars would most likely be green and blue and full of interesting lifeforms.

Our moon keeps us stable, we don't wobble on our axis. It also helps to keep the mantel and core liquid via the tides, all of that internal kneading via the tides most likely accounts for why earths interior is still so hot.

A question that creationists like to throw out there since the maths clearly show that even with radioactive materials the core should be pretty cold by now if earth is billions of years old. Our moon and the tidal influences it has would account for the lack of cooling.

So I have reached the conclusion that for a planet to maintain a stable climate and be habitable for long periods of time it requires a singularly large moon. I think the question of if technology using species arise hinges on how common are earthlike worlds with large moons.

I seriously doubt that by the time humanity reaches the point where it can manipulate and generate the energies needed to traverse the great distances between the stars that it will still be studying war, or for that matter be locked up in its social struggles.

Humanity sits on a razors edge. We currently have and have had the ability for 50 years or more to totally wipe out life on earth. As we find more powerful energies to play with, our ability to wipe ourselves our increases.

A third world war is impossible for humans to do. Well we can, but no one will survive. As a result of the discovery of nuclear energy and its application in weapons, we forced ourselves to find new ways to get along.

I suspect that for most species there is this period they must go through. Now do most end up retooling their social behaviors to peacefully advance to interstellar civilizations? It would be nice to think so.

However, I suspect that once humanity does reach the stars (if actually) we will discover world after world that is bombed out, dead, once holding life but the intelligent tool using species that arose couldn't master its passions.

Those that do master there passions will not interfere with the development of a primitive culture, and will allow nature to take its course. Thus I really doubt that the governments are in collusion with ET, or getting free technology.

I doubt any species that survived its on social struggle toward interstellar flight would hand a loaded gun to a child.
