If the human mind was simple enough to understand, we'd be too simple to understand it.
For that to be true, we'd have to all think and behave roughly the same.
By studying how others are different from ourselves, we can learn what we'd have trouble learning about ourselves through simple comparison.
The human mind isn't simple, but it doesn't mean it can't be understood.
I disagree just a little. We don't understand much in general about weird waves and stuff, still we created TV and WiFi and all kinds of crap. We don't have an intuitive take on it, still it can exist.
We can't fathom what goes on inside your head. Still we can create better and better brain imaging. So in a way we are one step ahead of ourselves.
If you can't make it come together in your head, just believe the aliens gave us the technology.
I know it's a bit off topic, but what you said about believing in alien technology is just for people that can't realize that we are able to do mind-blowing accomplishments.
Plus, like the big thing about Fiber Optics: Supposedly the story goes that it was reverse-engineered from an alien spacecraft, but yet since it was discovered we have upgraded it and increase the limits of this technology.
If there was aliens that could do these things, such as travel vast distances to come and watch us, don't you think that if we got that technology from them we wouldn't be able to upgrade it a few years later, they would be probably a millenium ahead of us and the technology would be a mind-fuck.
