Astronomy Picture of the Day!

This is the Sphinx in Egypt.  Lots of people have suggested that this was built by aliens or something, but it wasn't.  It was probably built by Egyptians or some other Africans.  Why would aliens waste their time building this crappy statue in the desert?  Really.  They can go zipping around the universe in their spaceships and go do whatever they want and then decide to make a statue with a human face in Africa?  If that's true, aliens are lame.  If I were an alien and I came to earth to build stuff, I would probably make a huge waterslide or something.  That would be way more fun than a creepy statue.
