As we know, many UFO sightings involve stars, weather phenomena, conventional aircraft and probably advanced human military aircraft-spacecraft. However, some of these flying objects may very well be extraterrestrial spacecraft, some type of vehicles or other anomalous phenomena. When certain objects like this are repeatedly tracked on radar and observed by very reliable witnesses (sometimes multiple witnesses), it seems reasonable to accept this possibility.
In a "multiverse" that we might be living in, there are many possibilities to wonder about. Could some UFOs come from other natural dimensions? Such other dimensions could be hidden from us though elements of physics and Nature that we do not fully understand. Because of the probability that some kind of intelligent other beings are involved, we could also wonder if they are friendly and good, hostile and evil or something altogether different that would be challenging for us to understand. And, could some of the beings not be biological, and some of the flying objects not solid, but be some sort of energy or quantum form?
Credible studies on the "near-death experience (NDE)" from a number of researchers have resulted in strong indications that there may be an afterlife or some other dimension that humans have often referenced in spiritual traditions. Seemingly related to the NDE phenomena, in 2008 the Baylor University Institute for Studies of Religion made public the results of a survey that many people found surprising. More than half of people polled believed they had been helped by a guardian angel during their lives. Interestingly, one in five of the people who responded identified themselves as not being religious. The survey of 1,700 people also asked questions about various religious topics. Fifty-five percent of those surveyed agreed with the following statement: "I was protected from harm by a guardian angel."
Agreement with the statement was consistent across educational levels, geographic region and religious denominations, according to Christopher Bader was the director of Baylor poll. Bader said in a TIME magazine article, "If you ask whether people believe in guardian angels, a lot of people will say, 'sure.' But this is different. It's experiential. It means that lots of Americans are having these lived supernatural experiences." He added that the amount of people reporting saying they believed they were protected by an angels was "the big shocker."
