As improbable as they may sound, you still have your own theories about various phenomena or maybe they're just beliefs that aren't commonly accepted. I have a few about aliens, how life originated, ancient civilizations... Tell us your ideas!

As to aliens, I don't believe they exist as extraterrestrial super-humans or humanoids. So that rules out UFO's as ships from other worlds. Aliens seem to be more of a demonic apparition. The stories come out about alien abductions and some rather hideous things they do to people.
Second, I don't care if you're made of carbon or glass, if a ship is shooting through the air at 800 miles per hour then suddenly stops and peels off from a 90 degree point there is no way a living being can live through that because of the G-forces it has to endure. Fighter pilots endure about 10 g's which makes them weigh ten times their weight. Now multiply that by a factor of five or ten and your body is going to turn to mush.
Which takes the fire away from the aliens said to have helped ancient Egyptians build the pyramids. When you have 35,000 people working 14 hour days under threat of death, lots of work can get done. Not much is said of the advancements made by the mind in anceint times. True they didn't have the technology we have now, but they had incredible knowledge of the world around them. I think it was India that had the first observatories. And the Middle East, they were math junkies! The human mind can accomplish alot, we just need to give ourselves credit so we can do more.

I must disagree with you on your acceleration theory. If you look to Star Trek (each episode has scientists working as consultants to make sure it is plausible) and Star Wars, they have intertial dampeners on their vessels. That reduces the inertia to where it won't hurt you so much and you do not feel as much stress on the body.
I do believe that there is alien life outside of our own. I mean, how arrogant can you be to believe that we are the sole inhabitants of all that open space outside of our atmosphere?
As far as those horror stories about what aliens do to people, I think the vast majority of them are unbelievable. Look at the people that get abducted, they're hicks! All of them are illiterate ... no wonder we haven't made first contact yet ...

they're hicks! All of them are illiterate ... no wonder we haven't made first contact yet .Wall ding it Clem, yew ben seein' too many a them gol durned green people, ah swar yew been hittin' that ol' joy juice, thar ain't such a thang as UFO's, tha's just Maynard's new trailer home all lit up with beer signs. J/K It is a real human fear about being alone, and what we call arrogance is really a fear that in the 32 billion light-year sphere of the universe, we're it! The conditions for life, let alone humanoid, are complex with very close tolorances. The stars have to be a certain type, like our sun. The sun is actually unique in its properties, most stars are multiple systems and any planets orbiting around them are going to have wildly changing temps from heat and cold. Other stars are unstable and blow out solar system-sized clouds of charged particles, and there are other stars that are either really huge, or the size of our Earth. To complicate it more, a life-bearing solar system has to be in the right position in our galaxy. Too close, and your solar system is likely to have a run-in with a star. Too far out in the edge, and there's not enough stardust to sustain or build planets or the life-giving comets. Not to mention galaxies have to be a certain way too, no collisions, no 30,000,000 solar-mass, dual black holes and exploding stars like the Andromeda Galaxy has.

I had forgotten about this thread...
Anyways, now I'm back... how can you be so close minded about life existing away from earth? Are you so completely sure that there is no other system supporting life in a distant part of the galaxy that you can say for certain that aliens don't exist? They don't have to exist as super humans/humanoids. They don't even have to exist in a form we're familiar with. The Hollywood depiction of aliens as green humanoids with almond shaped eyes and arms hanging down below their knees doesn't cut it, but if that's the way they want to imagine them...
<<The conditions for life, let alone humanoid, are complex with very close tolorances.>> Yet life forms have been found in hot springs and even in volcanic craters. You're just assuming that all life needs the conditions we require.

I have already given sound scientific reasons why I find that intelligent life somewhere near ours is either not existent or is going to be very difficult to find. Never did I mention Hollywood's take on aliens. how can you be so close minded Right! Yet life forms have been found in hot springs and even in volcanic craters. You're just assuming that all life needs the conditions we require.If the planet is too cold, metabolisms can't be sustained. If it's too hot the organism's cells will fall apart. Case in point, why hasn't life been found on Venus? Or Mars, Jupiter, or the other gas giants? They certainly fit the bill for an environment different from ours.

Well ... for one, we do not possess the technology to penetrate the heat of the two inner planets or the deeper regions of Jupiter. Nor do we possess the technology to take any in depth scans of Jupiter. We also could not send anything into Jupiter's atmosphere that could survive those winds.
Added: However, the moons of those planets past the asteroid belt are a very real possibility. It has been said numerous times that Saturn's frozen moon(s) could possibly support life.

<<Never did I mention Hollywood's take on aliens>> Many would. This is for them.
<<If the planet is too cold, metabolisms can't be sustained. If it's too hot the organism's cells will fall apart.>> My point being that their metabolism doesn't require the same conditions we require. You're just assuming that all life has to exist the same way life on earth exists. Maybe a hot/cold environment is conducive to these organisms.
<<Case in point, why hasn't life been found on Venus? Or Mars, Jupiter, or the other gas giants? They certainly fit the bill for an environment different from ours.>> But they're not the only planets (read: possible sources of life) in the universe. Life appears only when all the supporting conditions are present. Venus, Mars and Jupiter lacked in one or more of them, but don't you think it's possible that somwhere in the universe there is a planet that can support life?

So that rules out Jupiter, since it's said to be a failed star. It's way too cold for carbon and silicon-based life to exist. If life does exist, and I doubt it, on the moons of Saturn or Jupiter, they are one-celled and barely alive. they're not the only planets (read: possible sources of life) in the universe. Life appears only when all the supporting conditions are present. Venus, Mars and Jupiter lacked in one or more of them, but don't you think it's possible that somwhere in the universe there is a planet that can support life?Maybe one or two, but it's doubtful. The planet's we are finding are gas giants several times larger than Jupiter, or just hunks of rock. Life appears only when all the supporting conditions are present. Venus, Mars and Jupiter lacked in one or more of themBut if life does not have to exist in our own ideas of what should be able to support life. What supporting conditions must be present then? Any, one of the planets in our solar system have different conditions that should support life, not as we know it. Billions off planets outside the solar system match gas giants and planets such as Mercury or Venus. But so far none has been found. The Earth on the other hand, life is immediately apparent.

Well, as far as finding only gas giants and such ... those are probably the only planets big enough. Earth itself is a very small planet and probably much too small to be seen by a planet far enough away. Our telescopes probably just are not advanced enough to see those other Earth-like planets.

Doesnt anyone get why the gas giants are called gas giants?!
I mean the atmosphere is not made to yknow made for organisms to grow in.
What we need is a oxygen-nitrogen (or similar inert - ish) gas atmosphere.... and some carbon lying about and away we go. There must be other planets out there...but chances are i reckon we'll never make contact.

The stars astronomers are finding these planets at are too big, unstable, or both. So if Earth-sized planets are orbiting these suns, they are unable to support life. Most stars are double-suns i.e Star Wars, some are even triple systems or more. There are very few star systems with a single sun. And most of those stars such as Betelgeuse or Rigel 5 are super giants, or all the way down to dwarf stars. Our sun is unique in its stablity.
I don't care what make-up an alien has, if the star their planet orbits keeps burping up solar flares, they're not going to live long. Even some red-dwarf stars can blast out a solar flare that's several times bigger and more energetic than the solar flare that came from our sun last week. Those solar flares alone can (and did) knock out satellites and cause power surges. And that's only every 30 years or so. Other stars do it everyday for years.

Ive read that Saturn's Moon, I cant remember at the moment exactly which one, has a thick layer of ice covering over it, and that could crack eventually, but im more concerned about the SIZE of the moons.
Lets face it, a small moon just isnt large enough for developed lifeforms to grow.
Venus, I think, has been said to resemble an early earth, and if the sulfur clouds were to clear up, I have no doubt it would end up a planet very similar to earth.

Yes, it depends on the size of the body in space, too big, and its gravity increases, too small, and the gravity lessens. Hence, a living thing, of too big will not be able to stand up if in heavy gravity, but if the gravity is too little, there's nothing to stand against, and the organism might fail. Look at what happens to Russian Cosmonauts after six months in space. They've lost muscle bulk and thier hearts and bone mass are compromised.

It would still be way too hot I would think, and the planet would have to bleed off all the heat its been holding. Interesting possibilty though.
