Newly discovered planet may be habitable

It also doesn't seem practical that another species would be tooo much smarter than humans. All humans needed to get intelligent was (from my view) lions and tigers chasing us across the Serengeti in Africa. Need facilitates growth in intelligence. Since higher intelligence has stopped becoming an evolutionary trait, humans have theoretically been getting dumber and less intelligent.

This would seem likely on other planets as well. Unless they genetically engineer their own to be smarter (which is a definite possibility) then they would be getting dumber too.

Or there are other concepts of life altogether and we've only scratched the surface of existence/matter/dimensions/etc. where the rules that define our logic and reason could be thrown out the window. Again, another possibility

It's not a question whether people are individually dumber. The majority of people could be as dumb as bricks but still function in a high-tech society. You only need a fairly small proportion to figure things out and then teach to everybody else.

Take cellphones for example. Technically, all you need to teach someone with basic literacy skills to use it would be an instruction manual. Even putting them together does not require more than a high school education and training. All the brain work in developing and producing the cellphone was done by relatively few people.

Are people nowadays inherently smarter or dumber than before? Probably not. But the body of knowledge that people have easy access to improves all the time.

I've heard theories that airplane stealth is actually alien tech.

It's actually from the Nazis. When the superpowers were taking apart Germany after the second world war, they took some of their stealth designs and kept working on it. They also took rocketry and aerospace which is how NASA managed to get to the moon.

It's not alien tech. It's just refined Nazi technology.

You're talking about the radar stealth right? On the F-117A and the F-22... etc.

dont forget the american solid rocket fuels tehcnology that gave the us a massive advantage over the USSR for a long time, especially in ballistic missiles, then space stuff

the nazi stealth plane was a flying wing, with a lamnate skin instead of metal/wood so a much lower rader cross-section, if it had jet engines, and was a few years earlier, it would have helped win the battle of britain easily

the nazis had lots of crazy flying saucer ideas , which is most definately the origian of all the ufo sightings in the usa as these prototypes were beign tried out, but as we dont now go round in flying saucers, they obv. wernt too great (with every one beleiving in ufos it was great cover for the CIA to do testing, when a prototype was seen it got blamed on little green men)
