Many people believe that aliens exist and some also believe that aliens are visiting our planet regularly. There are certainly thousands of sightings and encounters reported each year, although how many of these can be substantiated is not clear. Certainly most if not all are not real alien sightings, and everything from sir force test planes to weather balloons are blamed. Whether aliens would have visited or not does however struggle under scientific scrutiny.
The notion of aliens existing has gone from laughable to an almost certainly over the last few years as scientists have furthered out understanding about the universe. There are billions of stars in our galaxy alone what have planets, and of those certainly there are many which will be capable of supporting life. On top of this there are billions of other galaxies as well, so the chances are that there is definitely life somewhere else in the universe. Not only this but it seems likely that there as once life on Mars billions of years ago.
If life on mars was established as a fact, even only bacterial, then it would certainly mean that there is life elsewhere also. Despite the fact that some planets are uninhabitable, if two out of the nine (or eight) planets in our solar system, then similar ratios might be expected fur supporting life elsewhere. Therefore the relevant question seems to be whether aliens have ever visited Earth rather then whether they actually exist in the first place.
The distances that aliens would have to travel in order to reach earth and to spy on us from the skies is billions of miles. That being the case they would likely have to travel at the speed of light, or would have had to have mastered stasis for long journeys. Both instances also dictate that aliens capable of visiting us would be thousands of years beyond our own technology, and would certainly be capable of hiding themselves when they got here.
It does seem odd that the people who tend to report seeing aliens and being abducted by them are invariably not otherwise successful people. You never hear about athletes or rich people being abducted, it always seems to be toothless backwater yokels and the mentally deficient. That isn't to say that there aren't any aliens as a result of the fact that people lie. However it would seem likely that aliens would reveal themselves to the governments or that they would abduct only the very best subjects to perform their tests on.
