1. The universe is pretty big
At the beginning of Contact, Carl Sagan talks about alien life in terms of our relationship to ants. We know ants exist, we see them all the time. I’m not sure if ants know we exist though they’ve surely interacted with us, but it’s not really worth our time to figure out how to communicate with ants and make sure they know we exist. That analogy makes the universe seem very big, no?
We live in the Milky Way Galaxy. There could be up to 170 billion additional galaxies in the universe. It is a widely accepted err in reasoning to make assumptions about a universal based on only one example. (And besides, in our one example, there is intelligent life so…)
2. Physical evidence
In 1991, people claimed that a UFO landed in France. Stanford University did studies on the plants and soil in the area and found unexplainable damage due to “powerful microwave radiation.”
3. Betty and Barney Hill
In 1961, Betty and Barney were traveling home from vacation in rural New Hampshire when Betty saw a light in the sky, like a satellite that grew bigger. Suddenly, they were 35 miles away with no recollection of traveling that distance. Their four-hour trip had taken seven hours, without explanation. Their clothes were torn and scraped. They drew separate but similar drawings of humanoid figures they vaguely recalled seeing and later gave similar accounts under hypnosis.
4. The sheer volume of personal accounts Of course, there is no safety in numbers. There are billions of people who thought the earth was flat and that their specific religion is The Truth. However, there are so many accounts of extraterrestrial contact. And there’s some consistency to them -- an attribute detectives use in trying to determine truth. What’s in it for these people though? What is the point of lying? It seems really embarrassing to have been abducted by aliens.
5. There’s basically a giant space ship at the bottom of the ocean
In 2011, a Swedish diving company was exploring the Baltic Sea looking for treasure when they found a 60 meter circular object at the end of a stretch that looks like a runway.
6. We’ve found evidence of non-intelligent extraterrestrial life, maybe
Former NASA scientist Richard Hoover says he has found fossilized microorganisms in meteorites.
7. This phone call
In 1997, radio program Coast to Coast AM, then hosted by Art Bell, aired a call from a frantic man who claimed to be an ex-Area 51 employee. Not only was the call suddenly cut off after the man claimed “they” would triangulate his position soon but the entire show was knocked off the air without explanation. After a few minutes, Coast to Coast went back on using back up equipment, but the caller never contacted them again.
8. Witness accounts of the Roswell UFO Incident
This Wikipedia article of “Witness Accounts of the Roswell UFO incident” is terrifying.
Notably, “In 2012, retired CIA agent Chase Brandon performed an interview with The Huffington Post talking about the Roswell UFO incident. He told that the debris recovered was not a weather balloon, and claimed it did not come from this planet.”
Perhaps it’s a massive conspiracy of a bunch of bored south-westerners, but how do you get so many people to lie about something like this?
9. Politicians have seen unidentified flying objects
Jimmy Carter and Dennis Kucinichboth say they have seen a UFO firsthand.
10. Stephen Hawking
The go-to cliché we use when talking about a genius, Stephen Hawking, said “to my mathematical brain, the numbers alone make thinking about aliens perfectly rational.” He also said we should probably be afraid of them, because if humans are any indication of how these beings would act, it’s bad. “We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet. I imagine they might exist in massive ships, having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach.” Gulp.
