Mayan Spacecraft

Look very closely at the picture and what do u see?  This is a picture taken of a carving found on the lid of the tomb of lord Pacal(silviaw).  There is something very peculiar about this carving. If you look closely it looks like a man sitting in an ancient spacecraft.  The man is in the very same position that modern astronauts sit in today.  His hands and feet seem to be holding controls and right at his nose you can see a tube that would supply oxygen. finally at the right side of the picture u can see what appears to be an engine and flames.  Could this be a spacecraft designed by the Mayans.  It sure does look that way

This carving is the depiction of lord Pacal at the time of his death falling into the underworld after death, or at lest that is what archaeologist what us to believe.  It looks eerily similar to a modern rocket. How would these primitive people be able to think of such a complex machine that is so accurate and detailed? Many believe that these ancient Mayans were visited by some intelligent life form from another planet. 

This may some ludicrous to some but how else would u explain this carving that was created in 683AD, way before the creation of modern machines(silviaw).  The Mayans temples also had to be built with the aid of extraterrestrial life.  How else would stones that weight tons be moved up a mountain and place precisely in place high on the temple.  Think about it, these people were living in a primitive time in a harsh environment where there sole goal in life was to find food and survive its hard to believe that they would have the time or resources to build such magnificent structures with out the help of some sort of extraterrestrial visitors.
