This is simply my opinion, so take it with a grain of salt. My opinion is that Extra-Terrestrial Intelligence (aliens) may in fact be a very distant future generation of us humans (maybe 100,000 years?). There’s documented proof in a popular science technology magazine (that I’ve unfortunately been unable to locate for this article) I read several years ago that said that due to the invention of the typewriter, and computers, video games and hand-held electronic devices, generations are being born currently with thumbs that are longer and stronger than they were prior to the 20th century.

The laws of physics, as far as we know, say that we can’t go the speed of light without some way of cheating, such as the theoretical wormhole. There is the possibility that we do come up with a way to travel at light speed or faster, which would obviously make space travel far less tedious, and much more convenient for our exploratory nature. I believe this may be how the ETI would be able to visit us.

Height is no longer a required trait, because as our societies grow, we want to fit more and more people into a smaller space. Skyscrapers, cubicles and other aspects of our increasingly mechanistic society are sort of forcing us to adapt to our environment, even though our environment is forcing us to evolve in different ways at the same time.

Many of us wear sunglasses, so I’m going to assume that some people are going to eventually evolve into having larger darker “tinted windows” over regular eyeballs to absorb the light provided by a star we associate with. If that’s not the case, then perhaps something cataclysmic has darkened the sun, such as several asteroid or meteor strikes, or perhaps living underground, or maybe even a supervolcano long-term eruption. If this were the case, it would also help us evolve an odd skin tone. We wouldn’t have as much melanin, or at least we wouldn’t develop as much melanogenesis (the reaction to the sun that creates a tan) if there’s not enough light.

Our noses are no longer needed for survival, so it would get smaller, I believe. We are already growing meat in labs, we have dietary supplements in pill or liquid form, so I think it’s just a matter of time before we can get all food in a much smaller form than it currently is, with all necessary nutrients. We won’t need mouths as big as that which we currently have.

Obviously, there is a paradox that says that one cannot travel back in time unless that time has the capability to get one back to their original future time, but as the adage goes; “If a tree falls in the woods and no one is there to hear it, does it make a sound?” How do we know ETI’s aren’t visiting? I personally think that aliens exist, but I don’t think they have visited us. To think we are alone in the universe is arrogant, and to think the aliens have visited earth with humans walking around is extreme, simply due to the efforts involved and the odds of traversing trillions of miles to find a 10,000 year window, and us making claims of ‘lights in the sky.’

Thanks for all the fish,
