The extraterrestrial hypothesis (ETH) is the belief that UFOs are vehicles from other planets that contain intelligent life for the purpose of visiting earth.
This being the most popular view among the public has been losing ground among those that have given Ufology serious study and thought over a long period of time. This is the perception that Hollywood has romanticized and advanced to the public but is probably the least likely. The chances of intelligent life climbing into to some type of space vehicle and visiting earth are pretty slim. Back in the 1930's this was the main theory put forward, since then physics and science have advanced to the point of making this theory almost irrelevant. It now seems that this is far too a simple explanation and in fact does not explain all the strange things reported by witnesses. The universe is not really as complex as one might think but it is full of things and knowledge that man has yet to comprehend or experience so the simple Hollywood explanation is probably far from realistic.
A UFO conspiracy theory is any one of many often overlapping conspiracy theories which argue that evidence of the reality of UFOs is being suppressed by various governments around the world. The prevailing thought is that earth governments, especially the United States and to a lesser extent Russia are in communication & cooperation with ETs and even allowing for a certain number and type of alien abductions.
As of 2012 portals have moved from theoretical to reality. A NASA-sponsored researcher at the University of Iowa has developed a way for spacecraft to hunt down hidden magnetic portals in the vicinity of Earth. These portals link the magnetic field of our planet to that of the sun.The existence of portals would go a long way in explaining the erratic and very short duration of many UFO sightings. Could it be possible that UFOs are only seen as they "uncloak" just prior to entering or exiting a portal. Since we know that portals exist between planet earth and the sun than it only stands to reason that portals would exist between galaxies. This would explain why we have not found anybody living in our immediate neighborhood. Maybe there is an abundance of life in the universe but not in our Milky Way. It could be they are traversing the galaxies using these portals or hyperlinks.
There is no observational evidence for wormholes, but on a theoretical level there are valid solutions to the equations of the theory of general relativity which contain wormholes . Because of its robust theoretical strength, a wormhole is also known as one of the great physics metaphors for teaching general relativity.This sounds very Hollywood but the idea of bending distance and time has been around for years. In theory this works and as a practical matter it could explain the vast distances intelligent life would have to travel to visit earth. This moves the ETH "From Another Planet Theory" to a entirely new level.
Ancient Alien Theory
This theory is gaining in popularity and it proposes that extraterrestrial beings have been visiting earth since the advent of man. It puts forward that early man was in direct contact with these entities even benefiting from alien technology to build various pyramids and structures around the world. There is some strong evidence that man was much more advanced than originally thought or did have technological support from unknown resources. Proponents suggest that this contact influenced the development of human beings and that man's DNA may have an alien variant. Due to mans lack of sophistication, knowledge and technology these aliens were misidentified as religious deities or Gods and their technology were evidence of their divine status. Early writings and scriptures,such as, Vedas Scriptures, various San-script writings (from India, China, Pakistan) and even the Bible seem to confirm this hypothesis.
Biological Theory (Atmospheric Life Forms)
When you stop and give this aspect of the UFO equation some thought this really has to be true. We know that life is tenacious, persistent and procreates just about anywhere at anytime under almost any conditions.
Why should this aspect of life be any different in space or in the greater universe. There are some laws that are truly universal,one of them is that life will find a way to flourish even in the most adverse and unexpected circumstances. To read aboutbiological UFOs.
Quantum Physics has been around since the 1920 but we are only just beginning to understand what it really is and what it means to mankind. When the possibility of more than one universe was mention it was pretty radical stuff. Even today quantum physics is just on the fringe of mainstream discussion. It is always hard for us to believe in things that we cannot see or fully understand.
While at a glance this may seem like just another strange theory, it contains many clues as to the fundamental nature of the universe and is more important then even relativity in the grand scheme of things . Furthermore, it describes the nature of the universe as being much different then the world we see.
Ronald Reagan (attempting to prove the existence of God) once said that he wanted to invite 20 atheist to the White House for a grand meal. After the meal was devoured he was going to ask his guest if they believed that there was a cook in the kitchen even though they never saw him/her. Sometimes you just have to believe in things that you cannot see, feel or touch.

Alternative Dimensions, Realms or Universes
Theories with more than one dimension of time have occasionally been advanced in physics, whether as a serious description of reality or just as a curious possibility. This theory is gaining momentum as more and more scientist believe in quantum physics. If you believe like many respected scientist have come to believe that there are multiverses (more than one universe) than it is not that much of a stretch to believe that beings could be traveling between universes (dimensions). This does necessarily mean that intelligent life forms are "time traveling" but they are simply traveling between dimensions, realms or universes.
Hollow Earth Theory
This theory proposes that the planet earth is either entirely hollow or
otherwise contains a substantial interior space. In the early 19th century an American eccentric, John Cleves Symmes (1779-1829), sought funding for an expedition to enter the earth through one of two 4,000-mile wide polar holes. Inside the Earth, he was convinced, a benevolent advanced civilization existed.
Though an object of derision to most people, some took him seriously, and the idea of a hollow Earth was championed in a number of books throughout the rest of the century and right into the next.Today, hollow-earthers believe flying saucers travel in and out of the polar holes. The people inside are descendants of Atlantis and its Pacific equivalent, Lemuria.
Earthlights, Ball Lightening Hypothesis
People have reported seeing ball lightning—a rare phenomenon that resembles a glowing sphere of electricity—for hundreds of years. Ball lightning often appears during thunderstorms and typically glows, spins, hisses, bounces, and floats. But scientists still can't explain what causes it, or even exactly what it is. (although in 2006 Brazil's physicist Antonia Pavoa believes he recreated it in a lab)
Related to the balls of light hypothesis is the earthlights or earthquake lightshypothesis which is based on the work of various independent researchers who have attempted to link UFO sightings where geological faults and geomagnetic fluctuations occur.
Man-Made UFOs / Back Engineered Technology
Governments and military have been attempting to emulate the performance of UFOs for decades. Pilots (especially since WWII) have reported that these craft have performed phenomenal feats and are capable of speeds that far exceeds our current technology. A good example of these efforts can be understood by reading about the AVRO Corporation which mysteriously and abruptly closed their doors in 1962. Follow this link for a list of the top 11 man-made UFOs that were made on earth.
Ever since the famous Roswell Incident of 1947 there has been serious speculation that the US military has attempted to back engineer UFO technology. In the event that the US military actually took possession of this type of technology it would have been only natural to do so. There have been claims by high ranking officials that other technologies were discovered at the same time which include, night vision capabilities, lasers, bullet proof vest to name just a few. Follow this link for a list of 12 technologies that were developed in the 1950's and 60's that may have had alien origin.
Other UFO Theories
TheoriesThere are other theories about where UFOs comes from and the reason we see them but they are too numerous to go into here. Some of those theories include.
- Cryptoterrestrial Hypothesis - The belief that extraterrestrial intelligence is not of our planet, but living among us.
- Electromagnetic Hypothesis - Earths magnetic fields affect human perception (similar to earthlights).
- Geophysical Locations - Certain geophysical locations have a strong effect on human consciousness (similar to earthlights).
- Hoax - The theory that all UFOs are fake and perpetrated on the public intentionally, for a short video on how to spot a hoax UFO sighting.
- Mass Delusion - For multiple witnesses, sometimes thousands to have a false belief bordering on psychotic, examples include Phoenix Lightsand the Belgium Wave.
- Misidentified Hypothesis - All UFOs are man made or natural.
- Paranormal Hypothesis - Paranormal activity causes the human mind to materialize objects.
- Phyccotronic Hypothesis - The belief that the UFO phenomena is the result of the manifestation of the human subconscious.
- Psycho-Social Hypothesis - This theory says people are a product of their social environment and human behavior explains UFOs, such as, wishful thinking, hallucinations, misidentification etc. This is a one size fits all explanation.
