Depending on where you look you will find that astronomers have identified between 20 and 400 or more potential habitable exoplanets or planetary systems in the Goldilocks Zone which could have life sustaining water. In the timeline of earth science we are in our infancy when it comes to space exploration. As human beings we base our conception of time base on our life-span. This is unfortunate when it comes to planning for what industrialization is doing to make earth inhospitable to life in our children’s lifetimes let alone 1,000’s of years from now.
We as a species tend to think of time based not only on how long we live but on the four seasons in our 365 day year.
There is no reason to believe that there aren’t other places in the universe where sentient beings with technology far more advanced than ours have an entirely different conception of time. What if they live thousands of years? This would make a trip across light years of space which might take a tenth of a lifetime doable. If they had giant craft with habitats where an entire society could live and thrive a voyage though space could take generations.
It is logical to think that they been able to do what we have done and explored space using highly advanced methods to find planets likely to be able to support some kind of intelligent life.
Back in 1977 the United States launched the first vehicles to explore space beyond out solar system, Voyager 1 and Voyager 2. “Voyager 1's extended mission is expected to continue until about 2025, when its radioisotope thermoelectric generators (RTGs) will no longer supply enough electric power to operate its scientific instruments.”
These vehicles aren’t even headed to planets where their mission would be to check for life, to determine if it is sentient, and if they find it to monitor what the beings are doing and send the information back to those on the home planet who would then decide what, if anything, to do about opening communication with earthlings sometime in a future they’d consider around the corner (remember they may live 1000 years).
Now let's think about about what these UFO’s may actually be. The first question most earthlings may ask is whether there are alien beings onboard. Again, consider that their conception of time may be based on their lifespan and while we think of the seven month journey it would entail for astronauts to get to Mars as doable, the hundred year journey to get from their planet to ours might be something they’d embark on if they lived 1000 years.
By this logic we can make a case that actual beings are on these craft.
It would make sense that before such beings undertook such a voyage they would have determined that Earth had intelligent life by one of two means I can think of. One would be by monitoring our radio traffic by their own more advanced version of our SETI Project. Another would be to have sent robotic probes first. It makes sense to this earthly mind that if there were hundreds or thousands of planets an advanced civilization discovered which might host intelligent life they wouldn’t send robotic probes to all of them, but then again this might be something they would do.
Keep in mind that their artificial intelligence would be far more advanced than ours so all the phenomena observed and photographed by reliable people could be explained by their being piloted by computers.
For all we know they are other civilizations who have fleets of spacecraft exploring the universe with their own version of the Star Trek mission statement: “Our five-hundred year mission is to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no being has gone before."
- They come from a different time.
- They come from an alternate universe.
- They come from a hidden civilization that may have been alien which has been here for many years (under the ocean for example)
- They are weather phenomenon or other natural occurrences.
