NASA Scientist: Aliens May Have Been Here And We Missed It

According to a NASA scientist, intelligent alien life may have visited earth and human beings missed it.

Silvano P. Colombano, a member of NASA's Intelligent Systems Division, wrote a paper titled “New Assumptions to Guide SETI Intelligence,” and presented it at the “Decoding Alien Intelligence Workshop.” In the paper, Colombano asserted:
Recent discoveries due to the Kepler project have identified planetary system as old as 10.4 Gyr (Kepler-10) [1] [3], and 11.2 Gyr (Kepler-444) [2]. Considering that the age of our solar system is about 4.5 Gyr, earth like planets could exist that are 6 Gyr, older than our own. Considering further that technological development in our civilization started only about 10K years ago and has seen the rise of scientific methodologies only in the past 500 years, we can surmise that we might have a real problem in predicting technological evolution even for the next thousand years, let alone 6 Million times that amount!​

He continued:

In light of these numbers, I think we need to re-visit even our most cherished assumptions: Interstellar travel is impossible or highly unlikely … Radio waves continue to be the major form of communication for thousands or millions of years … Intelligent civilizations would be based on carbon life … We have not been, and are not being... visited.​
Vis-à-vis the idea that alien civilizations might not be based on carbon life, Columbano stated:

I simply want to point out the fact that the intelligence we might find and that might choose to find us (if it hasn’t already) might not be at all be produced by carbon based organisms like us. How might that change the above assumptions about interstellar travel? Our typical life-spans would no longer be a limitation (although even these could be dealt with multi-generational missions or suspended animation), and the size of the “explorer” might be that of an extremely tiny super-intelligent entity. And how might this change our assumptions about openness or desire to communicate with other civilizations?​
Columbano posited that it was well within the limits of reason to speculate that alien life had visited earth, writing:
It seems to me that SETI has ignored (at least officially) the potential relevance of UFO phenomena for three reasons: 1) The assumption of extremely low likelihood of interstellar travel, 2) The very high likelihood of hoaxes, mistaken perceptions or even psychotic events in UFO phenomena, and 3) The general avoidance of the subject by the scientific community.
I think the approach the scientific community could take, instead, is very similar to what SETI has done so far: find the signal in the noise. In the very large amount of “noise” in UFO reporting there may be “signals” however small, that indicate some phenomena that cannot be explained or denied. If we adopt a new set of assumptions about what forms of higher intelligence and technology we might find, some of those phenomena might fit specific hypotheses, and we could start some serious enquiry.​

Mods, please merge this with the Aliens thread. ;)

Call me crazy, but I think it could be possible. There are many ancient structures that would be near impossible to construct even with today's technology much less with the primitive tools long, long ago. There are depictions from civilizations all across the globe of "astronauts and space ships" and tales of advanced civilizations like Atlantis. I believe there was a far more advanced race on the planet many centuries ago which mysteriously vanished

Probably drowned in the flood with the dinosaurs.

Imagine all the grains of sand on all the beaches and deserts on our planet. There are more stars than that in the universe. The odds of us being the only planet with intelligent life seems pretty unlikely to me.

As far as them traveling here, that's another matter. You have to imagine not just greater technology, but different laws of physics for that to happen. However, we've come from sharpened stones to putting a rover on Mars in less than 100th the timeline of human existence so who knows what could be achieved in the next 1000 years.

Does any rational person actually believe we're the only intelligent life in the universe, or even in our own galaxy for that matter?

Seems extremely likely but scientists require rock solid proof and at this point none exists.
Proof of molecules and atoms once did not exist. In the 10th century proof of the North American continent didn't exist for Europeans. Exoplanets hadn't been proven when I was a kid.

It's true we can't say it is until we prove it is, but the numbers are in the favor of likelihood of other intelligent life.

There could be as many as 3 trillion galaxies in the solar system with 40 billion habitable earth-like planets. There are thousands of earth-like planets in the Milky Way alone. The odds of no other forms of life in the solar system are minuscule.

This possible alien life, if it's intelligent, why should we think it wants anything to do with us?
If it's anything like us, which is anyone's guess, they would likely want to study us. If they have the curiosity and intelligence to make it out into the universe they would likely be creatures of science.

As far as the UFO sightings, I always imagine them yelling at their version of Gary Busey for forgetting to turn the lights out on the craft as they hover over our planet.

The only thing more ignorant than your statement, is that someone "agreed" with you.

That degree from goonville is really paying off.

At this point even soft squishy proof doesn't exist.

Regarding the "rock solid proof", a lot of people like myself are a little geeky about this stuff and look forward to the day where the internet blows up with news of contact with other beings or even proof of life on another planet. If history tells us anything it won't work that way.

Someday scientists will find something that indicates the possibility of life. They actually already have with the seasonal fluctuation of methane in Mars' atmosphere, but that's a long shot. Most of the scientific community will shoot holes in their theory until they find more evidence. Eventually it will tilt to the side of more likely than not. After some lengthy ongoing debate we will accept this new neighbor in the galaxy as fact. But it will be a long process not a headline making event.
