It's sort of disc shaped and shiny. It's too big to be a plane moving across the sky and too high in the sky to be a radio tower light of any kind. So what is it? It's a picture I took of the moon one morning as the sun was rising using my crappy cellphone camera. Yet it looks quite odd. It doesn't look like the moon.
The point here is that it's easy to find UFOs in the sky. However, take a moment to ask a few questions before jumping to conclusions. You may very well find a natural explanation. Even if you don't, there's still a likely natural explanation. Don't jump to conclusions and claim this is a government cover-up of aliens taking over the Earth. It's not. It's simply something you don't have enough evidence at the time to explain. For more information, here's a great site discussing many of the greatest UFO hoaxes of all time.
