"The Fermi paradox is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilizations and the lack of evidence for or contact with such civilizations.

According to some observers, the extreme age of the universe and its vast number of stars suggest that extraterrestrial life should be common. Discussing this proposition with colleagues over lunch in 1950, the physicist Enrico Fermi is said to have asked: "Where are they?" Fermi questioned why, if a multitude of advanced extraterrestrial civilizations exist in the Milky Way galaxy, evidence such as probes, spacecraft, or radio transmissions has not been found. The simple question "Where are they?" (alternatively, "Where is everybody?") is possibly apocryphal, but Fermi is widely credited with simplifying the problem of the probability of extraterrestrial life. Wider examination of the implications of the topic began with Michael Hart in 1975, and it is sometimes referred to as the Fermi-Hart paradox.

There have been attempts to resolve the Fermi Paradox by locating evidence of extraterrestrial civilizations, along with proposals that such life could exist without human knowledge. Counterarguments suggest that intelligent extraterrestrial life does not exist or occurs so rarely that humans will never make contact with it.

A great deal of effort has gone into developing scientific theories and possible models of extraterrestrial life and the Fermi paradox has become a theoretical reference point in much of this work. The problem has spawned numerous scholarly works addressing it directly, while various questions that relate to it have been addressed in fields as diverse as astronomy, biology, ecology and philosophy. The emerging field of astrobiology has brought an interdisciplinary approach to the Fermi paradox and the question of extraterrestrial life."--wikipedia

To the objective (or open minded ) person there are several possibliities:

1. Earth is unique-- Earth is the only planet capable of supporting life as we know it.
2. Earth is not unique in that there is life elsewhere but there are no other advanced civilizations in the universe.
3. Earthlike planets are extremely rare therefore any advanced civilizations are to far away for us to contact.
3. Earthlike planets are not rare, there are many civilizations out there but they are so far ahead of us technologically that they do not wish to be contacted.
4. Earthlike planets are not rare, there are many civilizations out there but their form of life may be so different than ours that communication may be impossible.
5. The Zoo hypothesis--we are being deliberately isolated by some advanced race wishing to protect us or cultivate us technologically.
6. We have been contacted but our governments feel that the general public is not "ready" for such a discovery and the aliens have respected that viewpoint.
7. They are already amoung us but we cannot see them (deliberate hiding or so differnet that our eyes can't see them)and our government doesn't know.

you can probably add to this list.

MOST (but certainly not ALL) UFO sightings can easily defined.
You see something in the sky
You can't identify it.
It is flying.
It is by definition a UFO.
That is obvious an simplistic, but having seen weather balloons with strings of lights hanging from them drifting and undulating, (you can see the lights but not the balloon or the connecting cord if it is far away) I can easily see why they would be reported as UFOs.
Unusual motion of a bright object? I've seen the landing light of a aircraft coming straight toward me. It can be seen from many miles away. It appears to hang in one spot. You can't see the airplane.
The aircraft turns and the intensity of the light is less but looks like it SUDDENLY accelerated from a dead stop.
As I said, once it is identified, it is no longer a UFO.
I've even seen kites and radio controlled model airplanes from a distance that made me do a double-take. Identification is not always easy.
Keep watching!
There ARE sightings that are never identified and don't make sense, but I have only seen one and the details are too few to consider it noteworthy compared to some stories I've heard. .

i personally have seen 3 UFO's the first one was when i was a kid , around 8 years old we were coming back from a local fair, and was driving through town, it was a clear cloudless evening. when we got near the local power plant around a corner, there was a huge gas cloud, over the power plant , and lightning bolts were shooting into the cloud from the power plant , all the local lights in the area started to dim as more and more bolts shot into the cloud. it was almost as if the cloud was sucking the power out of the power plant at a unreal speed. the bolts slowed and finally stopped shooting into the cloud. then i heard a low humming noise and a kinda box shape object shot out of the cloud above the power plant , and hovered around 500 ft or so, then shot straight up , and out of site. we stood there , and watch untill the gas cloud disappeared, and we went home , all speechless, and none of us really willing to talk about what we had seen. the other stories are more detailed, and would take too long to post here... and just so everyone know i am not one of those tin foil hat wearing odd fellows .

Yes, twice.
One night, my wife and I were camping out, in the country, and it was a clear sharp night, with a lot of stars. We watched a bright shining light (white), come out of the south, went across the sky about half way, then it stopped, made a "L" shaped turn and went real fast to the east. To my knowledge, there is no known airplane that can fly that high in the sky, come to a complete stop, then make a "L" turn, and fly off real fast. It was a UFO.
The second time, we were setting on the back porch step, looking at the stars, and a object, like a string of green beads, was floating vertically across the nighttime sky, way up in the sky. It was weird....
