you need just 2 for depth perception, 3 is a odd number...would take more energy to accomplish nothing...evolution likes symmetry.
I am skeptical of the story, not because its aliens or whatnot, but because biologically it doesn't make sense...odd numbered things don't do too well in nature.

Remember, these were primitive people from China.
The "three eyes" description could easily have been due to 2 eyes plus some sort of head or helmet mounted device. Recall the lighted round mirror surgeons sometime wear, or the night vision device U.S. soldiers have mounted on their helmets.. Point is that the 3rd eye doesn't have to be literally a 3rd eye. It could be some other kind of device that was called an "eye" by a frightened primitive person.

Good point... but...
One can only assume that the way life evolved on earth is not the standard for the way life might have evolved somewhere else in the universe based on a tons of different factors.
Similarity might be the norm but it doesn't mean we have to close our minds to the unusual.

Actually, although you have a point...sort of...that evolution elsewhere may be very different than here, there is also some standards
such as, all life, be it on earth, or in a different galaxy, will have ways to hunt and eat stuff...reproduce, etc...so you can start defining loosely some common traits.
the 2 eye verses 100 eyes discussion is one of those things...predatory eyes are two in front...enough for depth perception, enough to give the advantage, and not too much to weigh down the brain with processing redundant data (there is a reason insects aren't even remotely on top of the whole food chain...they are unable to process much more considering their brains are saturated with processing just the endless redundant data)
If there is different spectrum seeing, again, it would be 2 eyes (making 4) for depth perception...
But I think anyhow Cent makes the best point...may not have been an eye at all
Only problem with that is, surely there would have been remarked about how one eye was different than the other two..
meh, who knows
Tell me, how can you make assumptions about what it would be like with very little evidence to support your theory?
In the end your just guessing, stop pretending like its deduction, fact is there are no facts to make deductions from clearly showing that you sir: Fail at logic.
It is interesting these stories were written and seems to corroborate stories we hear today. It could be the first works of fiction or a recounting of stories told by their ancestors.
All these people who say "this is impossible due to nature" have only the slightest glimpse as to what nature really is. Everything else spewed out is a second hand retelling of a NASA Theory told as factual evidence. It serves no good purpose to make assumptions based on very little facts, if any.
Everyday we learn something new about planets, life, the universe and NASA even admits we know very little and most is theoretical. So with that said, stop talking like you guys have been planet hopping for millennium. You sound very dumb and it's not making the conversation constructive, it serves the very opposite actually. This site is full of know-it-alls and the fact is, no one knows very much if anything about this that visits here, those who do can honestly say, it's mostly theory.

Thats actually a fair point...camera, light, etc...
I am wondering how a man 500 years ago would write about us if we teleported a spec ops person back there and he just glimpsed the full gear..
helmet with cameras and lights on it, rods that shot lightning and thunder, etc...reading an account literally would seem stupid, but taking it into perspective would make sense.

What facts can you provide to prove that evolution is standard throughout the entirety of the universe? Not theories, facts.
I've researched and everything that speaks of this, including the big bang is theory based hypothesis which sometimes is proven wrong when a new variable is introduced.
How can you be sure there is not one variable out there that makes a 3rd eye useful?
I know I can honestly say that I am not sure if its possible or impossible but ill leave my mind open for now while learning more about this before making a hasty conclusion. As should everyone else.
Also your argument about insects and them being at the bottom of the food chain for the reason of having to process redundant data, your talking miniscule insects here. The brain of these aliens would be significantly larger then an insect, and it's only one extra eye.
I doubt their would be much strain on such intelligence had it existed with a third eye so that argument, although it stands to reason, doesn't necessarily make perfect logical sense.edit on 20-7-2011 by EspyderMan because: (no reason given)
Interesting Fact The tuatara has a third eye on top of its head. This extra eye has scales over it, so the tuatara can't see out of it or move it around. But the extra eye can feel sunlight. Some scientists think tuatara use their third eye to let them know if they have had enough sunlight.
