Deathbed Confession Says Aliens Were at Roswell
xnuandax writes "The army's explanation of weather balloons in the Roswell, New Mexico incident 60 years ago has been dealt a serious public relations blow. Late Army Lt. Walter Haut had signed a sealed affidavit prior to his death last year asserting that he had witnessed the wreckage of an egg-shaped craft and its extraterrestrial crew while working at the Roswell Army Air Field. An article at News.com.au reviews how Haut had worked as public relations officer for the Roswell base and was involved in the original weather balloon explanation of events at the time. This recent evidence would seem to confirm speculation that egg-shaped saucers are notoriously difficult to fly safely at low altitude."
As much as I want to believe aliens are among us, it just doesn't make sense that a civilization advanced enough to cross interstellar space would crash in New Mexico. And the chances of aliens being humanoid in appearance are close to zero.
First off, it may be that the visitors have a limited budget, just like anything we do does. One allocates the risk based on this budget. Even though we may have the money to make or buy the Ultimate Safest Volvo, it does not mean we will.
As far as appearence, here are some possibilities:
1. They are interested in us *because* we look like them.
2. They are us from the future.
3. We are a degerate form of them.
4. The human-like form is somewhat universal after all.

Big deal 1 guy admits it, the video below shows 22 of 400 senior Government, NASA, Airfoce & other top Military personel admitting it on National/International television that aliens are real & Gov has been hiding it.

Yeah it's almost 2 hours long, but it will blow your mind!
I wonder how much longer they can keep denying the more than obvious.
Nuff said.

No trees were killed in the making of this post; however, many trillions of electrons were horribly inconvenienced.
I believe the first F-117 Stealth (invisible to all high tech anti-air defenses) was brought down over Serbia by an AK-47. The Pentagon story is it was brought down with an SA-3 with a hacked radar, but either way a primitive tool brought it down.
But you also have convergent evolution. Thus, the eye has arisen independently some 22 times in the tree of life, IIRC. You mention the head, which has been a reproductively successful adaptation. What I'm saying is not that the first successful body-plan that happen to evolve was the head and thorax, so that's what all descendants got. What I'm saying is that the environment selects body-plans that are beneficial, which is why we observe example of convergent evolution, such as legs and wings in chordates and insects.
As an example, we have radially symmetrical animals, such as jellyfish, and bilaterally symmetrical animals, such as chordates. Stephen Pinker talks about how any animal navigating an environment with gravity would benefit from a bilaterally symmetrical body plan. Thus we might reasonably conclude that any life form on a planet that can randomly evolve a bilaterally symmetrical body would have reproductive success. Once you have bilaterally symmetry, I don't think it's too much of a leap to think they could evolve legs, useful on land and water, and heads with brains. Once you have legs, then you can evolve manipulative appendages, such as hands. If you have two legs, you might not do too much manipulation with them, because you benefit more from them being evolved more for walking than manipulation. But if you have an extra pair of legs ( if the animal is bilaterally symmetric, it probably wouldn't have 3 or 5 ), then you might start using the extra pair to manipulate objects all the time, instead of walking on them. Then the lineage would experience selection for better and better tool manipulation with its extra legs -- so they become 'hands'. Once you're walking on one pair of legs, and manipulating objects with the other, bingo! -- you've got a humanoid.
So once you can accept that a body plan of a torso, which has all your organs for digesting food and eliminating waster, and a head, for sensing the environment and thinking about it, is a body-plan that was successful and therefore selected, rather than just a random body plan that was just passed on, it's not to much of a leap to say that one of those walking animals stood up and used two of those legs to manipulate objects instead of walk. And if convergent evolution can happen among independent lineages here on earth, why not in similar environments, like a rocky planet, somewhere else in space? Is it too much of a stretch to imagine wings or eyes evolving in extra-terrestrial animals? How about then legs or arms and hands?
To describe a 'humanoid', all you need is an upright torso with a head, two legs for locomotion, and two manipulative hands. I don't think it's too far of a stretch to say that such a body plan for an intelligent, conscious, tool-making creature would be selected in a convergent evolution scenario.
Then the question is, animals of what body-plan would be developing vehicles that can travel interstallar space? Elephants and dolphins might be as smart as we are, but without appendages to manipulate objects, they can't really build tools, buildings, or vehicles. Once you have manipulative appendages, then evolution might select animals who can better manipulate objects and their environment. That means they get smarter. Learning and technology develop. Then you get tools, buildings, and vehicles. So, there may be a lot of different intelligent animals with weird body plans, such as a radially-symmetrical jelly-fish like creature. But without the manipulative structures, such as hands, we wouldn't expect them to be building space ships, and winding up landing or crash-landing on other planets.
Computers are useless. They can only give you answers.

I'm sorry but this is just not a conversation that makes any sense. We haven't even got the vaguest idea of what the boundaries are for the conversation "What is Life?". The idea that a species evolving in a different environment, I mean really different, is going to in any way resemble human beings, is simply ludicrous. You gotta cut back on the Star Trek, the numerous humanoid aliens there are simply a function of make-up vs. CGI budget.
We (human beings) are running around with DNA from an ancient ancestor that had 5 fold symmetry, 4 limbs + head, 5 fingers on each hand, five toes on each foot, and five primary orifices in the skull (think inverted appendage.) Before that we inherited DNA from a worm... if you look at a human body morphologically we're worms that evolved better means of locomotion, and the ability to manipulate our local environment. Any alien you see owning a head with a face you can recognize, a spine, and limbs would have had to evolve on this planet. There are trillions of evolutionary paths that could have made life on earth wildly different, and to assume the path that produced us is the only path that could have produced sentient life with the ability to manipulate it's environment is not only myopic, it's homocentric to a fault.
I won't argue that certain structures would prove useful on earth and evolve repeatedly given our enviornment. Even on earh, however there are vastly different organism operating in wildly different circumstances, no light, crushing pressure and heat, sulphur as an energy cycle, even organisms that exist in ultracold and environments lacking oxygen. That's just on this planet, using precisely the same DNA, and carbon based biology.
I could easily imagine life based on completely different chemistry... carbon will usually be the most likely chemical backbone, though at higher temperatures sillicon and metals might combine in very interesting ways. Sensing is a vital characteristic of life, but organs of sense might be tremendously different for another species. They might sense any or all parts of the electromagnetic spectrum, and do so with organs very different from ours. How and what they consume and excrete might be very different than what we understand... even on earth what animals breath out, plants breath in... what might setient beings who move as slowly as plants occur to us like? Plants have powerful sensory capabilities, but they are very unlike humanoids.
On earth the octopus is a prime example of a mollusk well on it's way to becoming a technological intelligence. Here's an animal with much in common with human beings but also very alien... communication through melenophores... that's way ourside our normal thinking, and this is an intelligent terrestrial species. How much more different might a being be that evolved in a cold methane lake, or whose fundamental chemisty is composed of complex sugars instead of proteins.
You're going to have to stretch your head a whole lot more if you're goin to imagine life elsewhere. The chances of it being a lot like us is slim at best. Anyway you're going to have to sift through a lot of microoganisms before you find any larger than unicellular life out there. Of course, there's nothing preventing unicellular communities from becoming sentient. That's a kind of life we should be very careful not to miss, simply because it doesn't look like us.
