Well, I think the greys/grays reptillians etc. are all made up and people having hallucinations/fantasies.
(other planets containing life however... yes, that most likely exists.)
My reason for this belief I typed out below... I know it's a lot but I feel I should back up my extreme opinion with some real information.
As of 14 April 2010, 452 extrasolar planets have been confirmed.
Currently, Gliese 581 d, the fourth planet of the red dwarf star Gliese 581 (approximately 20 light years from Earth), appears to be the best example yet discovered of a possible terrestrial exoplanet that orbits within the habitable zone surrounding its star.
Out of this VAST universe the odds of another planet being in the "habitable zone" and containing life definitely IS a possibility.
As far as we can tell the closest possible alien life would still be....light years away from us. That would mean a minimum of 20+ years traveling near the speed of light.
Let's just say that based on our science which is really solid knowledge most likely the other life forms are unable to travel the distance. Honestly, I don't imagine space travelers willing to travel years 10+ 20+ 30+ 40+ (years in fact) which would be necessary in order to reach us.
Sure, I will admit that maybe they have technology beyond ours.
But, I doubt it. You just cannot go the speed of light or even too close to it.
Here is an excerpt on what happens when you TRY to go the speed of light: Let's assume that your engines are powered by tapping into some external energy source, so you don't have to worry about carrying fuel. As you get going faster and faster in your starship, you are putting more and more energy into the ship by speeding it up, so the ship keeps getting heavier. (Again, I should really be saying "massier" not "heavier" since there is no gravity in space.) By the time you reach 90 percent of the speed of light, the ship has so much energy in it that it actually has about twice the mass as the ship has at rest. It gets harder and harder to propel with the engines, because it's so heavy. As you get closer to the speed of light, you begin to get diminishing returns — the more energy the ship has, the heavier it gets, so the more energy that must be put into it to speed it up just a little bit, the heavier it gets, and so on.
The effect is even worse than you might think because of what is going on inside the ship. After all, everything inside the ship, including you, is speeding up, getting more and more energy, and getting heavier and heavier. In fact, you and all the machines on the ship are getting pretty sluggish. Your watch, for instance, which used to weigh about half an ounce, now weighs about forty tons. And the spring inside your watch really hasn't gotten any stronger, so the watch has slowed way down so that it only ticks once an hour. Not only has your watch slowed down, but the biological clock inside your head has also slowed down. You don't notice this because your neurons are getting heavier, and your thoughts are slowed down by exactly the same amount as the watch. As far as you are concerned, your watch is just ticking along at the same rate as before. (Physicists call this "relativistic time contraction.") The other thing that is slowed down is all of the machinery that is powering your engines (the dilithium crystals are getting heavier and slower, too). So your ship is getting heavier, your engines are getting sluggish, and the closer you get to the speed of light, the worse it gets. It just gets harder and harder and harder, and no matter how hard you try, you just can't quite get over the light barrier. And that's why you can't go faster than the speed of light.
------------------------------------
The only REAL possibility I would say, and this would be CRACKPOT theory mind you... is that matter does not exist and the aliens can teleport from one spot to another because they are not really moving.
