Another one of those "has to be very real or a complete fake." It's a shame so many people are making fake videos. This one is awesome except for the constant question of "is this real?" Unfortunately it looks like it could be fake. http://www.youtube.com/watch?v=BTi0S1ZUYF0
Watch this. Watch at least the beginning and the part at 5:40, where they slow it down. When they enhance it, you can clearly see a strange (alien?) creature reaching out from mid-air and grabbing this boy. Is it real? A lot of people believe it is.
Alien or rock? What are the odds that this object was formed by wind or water erosion, especially considering how different it is from anything else in the area?
