Yes, I do, and so do a lot of other serious investigators. There are still many unanswered questions about their origin and agenda, but there have been too many excellent eyewitness accounts of alien encounters, to simply dismiss them.
We must separate what is depicted in movies and other media with what has actually happened in real life.
Question #2: What are some possible explanations for what occurred in Roswell in 1947?
There are various theories about what happened there in 1947. Some believe that an actual spaceship from other planet crashed there, while others believe that it was nothing more than a test balloon launched by our military.
Actual eyewitness testimony from reliable individuals tells the real story, that a craft of unknown origin crash landed.
Question #3: Do you believe the government is attempting to cover-up the incident?
Yes, I do. The test dummies that they say were mistaken for alien bodies were not even used until several years later, and why would there be a complete surrounding by the military of the crash debris and total cleanup of the site for a balloon.
Question #4: If so, why?
I believe that our government is afraid for this information to reach the general public. There are a number of reasons for this. One is the control of information.
Another is that our government is afraid the public would panic if they knew the truth.
Also, there would be major changes in the world economy, religion, and resulting social upheaval.
Although some governments have released UFO files, how do we know that we are seeing all of them or just what they want us to see?
Question #5: Why do you think the aliens are here?
This is a good question with various theories. There could be a dying planet that needs certain resources that can be obtained here in Earth. They also could be attempting to create discourse with us for further exploration and understanding of our world.
There is also the frightful possibility that an alien race might be attempting to create a plan for taking over our planet.
Question #6: Do you think the accounts of the supposed (Roswell) witnesses are sound?
The correct answer to this question is that some are, but some are not. There have been a number of witnesses whose testimony has been found to be fraudulent, attempting to gain notoriety or fame.
However, there are many sound, reliable witnesses who have sought nothing in return for their accounts of what happened there, and only wish for the truth to be known.
Question #7: Why do you think so many people attempted to involve themselves?
More than likely, they have wanted to feel important, that they were privy to a major event. As I mentioned earlier, some of them were attempting to gain financial compensation for their stories, and some wanted to etch their name in the history books.
