I think there must be other inteligent life with the size of space.

The most interesting theroy as to UFO sightings for me has been that they are not from other planets, but humans traveling from the future.

I dont know the science of it. From what I understand physists have theorized time travel is possible. And with light speed limitations it is almost more plausible that we are being visited from out own planet.

This idea seems to answer alot of questions related to UFO's.

Why would a superior being feel the need to hide from us? Don't want to alter the future by disturning the past.

Why do they have similar body structures?
With all the possibilities of life, why woul alien sitings being in huminoid form.

Why are they here? Seems like a highly advanced being would ahve no use for us. With such superior technoligy, I cannot imagine we have anything they need. Time travelers, may be changing a few things to prevent disasters.

Movement of UFOs. Reported to be skipping across the sky. TIme travel seems to account for that.

Im not a science person, merely a law student. Not saying I believe in the above, just that I find it very interesting.

Time travelers makes a lot of sense when you consider that in the future free porn will be history.

It does seem kinda vain to think that we're the only populated planet in the universe, but it seems highly unlikely that we'll ever see any evidence to the contrary.

Just how confident do you feel about this statement? I think you underestimate just how awesomely unpredictable the effects of advances in science and technology tend to be.

[/ QUOTE ]

Our own advances in science would seem to indicate it's very unlikely aliens have ever visited Earth.

For this to have happened, basic life must have evolved on another planet. Then it must have survived, and evolved into "intelligent" life. That life must then go through accumulating the massive amount of knowledge and technology necessary for light-speed space travel. It would then need to actually TRAVEL here, which would take a varying degrees of time depending on galaxy of origin -- but even within the Milky Way, it'd be a long trip. That's assuming they had a reason to come to Earth first, which they wouldn't as they'd have no way of knowing life existed here.

It seems to me that the barrier of traveling at light-speed alone almost ensures we have not been visited.

If the aliens have the technology to come here, what makes you think they also wouldn't have developed a stardrive that goes faster than light?

The facts I provided, combined with a google search, will provide more than enough proof that jason_t's math doesn't apply.

Yes but we already knew that. What do we have against the real stuff: http://en.wikipedia.org/wiki/Rare_Earth_hypothesis

[/ QUOTE ]

"The rare Earth hypothesis is a response to the Fermi paradox which explains why we might expect a planet such as Earth to be very rare. Combined with the additional assumption that an Earth-like planet is a prerequisite for the development of advanced life , this offers an explanation for the current lack of evidence of extraterrestrial civilisations."

This seems like the absurd part.

I still need to read the book, but "assumption" is definitely the wrong word here. They look at several aspects of our planet and its history and give reasons why those aspects are, in their opinion, necessary for complex life. On top of this they try to show that for a planet to have all of these aspects in combination would be very rare. Once I get this book I'd like to go over each point they make and see if it holds up.

I've finished the book, and will post an ongoing review and critique in this thread in Science, Math, and Philosophy. (I hope moving it there was not a mistake).

That is exactly how i feel. I "know" there is intelligent life out there, but i doubt we will be around long enough to find out.
