UFO's: I have always been a science nerd. Einstein is the closest thing to a hero for me. I understand the importance of witnesses to events as a means of establishing validity to claims. I paid close attention to events that involved multiple witnesses. But, because I couldn't duplicate anomalous experiences the so called personal reports never got to the level of belief for me. UNTIL... my family and neighbors actually witnessed a UFO. I combed the neighborhood for other witnesses because I didn't want to just trust my own and other family members judgement. Altogether I found 3 neighbors that witnessed the same thing. Also a friend who lived 3 miles away witnessed the same event on the same night. As it turned out that night was one of the busiest nights for UFO sightings all over the world up to that point in time (NUFOR report).
So, I have become a believer in UFO's. I don't believe in all UFO reports. I only believe the ones that are similar to what I experienced. I don't believe in the anal probing abductions reports that are retrieved through hypnosis. I also don't believe in reports that are witnessed by only one person.
Do I believe these are visitors from planets in our physical universe. It depends on what you consider our physical universe. No I don't believe it is likely that they have traveled millions of light years. Instead, I believe it is possible to jump dimensionally. The behavior of the craft we witnessed suggested some sort of coordinate linking up with a kind of beam to energize the jump.
Do I believe anyone should believe my story? No. But, judging from the total picture of half-way credible reports I believe there will one day be some kind of ongoing contact.
Conspiracy theories are conjured up by the same mentality that believes in God. People want to believe that someone is in control. God. Secret Societies. Satan. Even the concept of "free-will" is an illusion that emerges from the idea that there are agents who control. We have no soul or little man inside that's pushing the buttons. And there is no big man outside the universe who is in control.
