Indiana Jones and the Kingdom of the Crystal Skull Spoilers: Aliens Attack!
Take this as a rumor, but we've heard the following about Indiana Jones and the Kingdom of the Crystal Skull.
To celebrate Close Encounters of the Third Kind's 30th anniversary, Steven Spielberg has dusted off those rubber Extraterrestrial dummies for a cameo appearance in the final (we assume) installment of Indiana Jones.
This may sound ludicrous, but Harvard lecturer Dr. Marc Zender makes it seem as though aliens may play a role in the film.
He explains that crystal skulls were once displayed in museums across the globe as proof of ancient Mayan grinding technology, but they're actually all fakes, most likely manufactured in late 19th-century Germany.

Can you imagine aliens popping up in Indiana Jones and the Kingdom of the Crystal Skull?
"These things are big crystals, and people started thinking of them as these super computers of past civilizations," Dr. Zender said. "If a silicon chip can hold tons of information and data, imagine what a gigantic 11-pound crystal can hold. So maybe this skull has stored all of the lost knowledge of the Mayans or Atlantians, or ET."

Yup the thing turns out to be alien built the pyramids and the ship below it.
the skull belongs to one of the 13 alien leaders....once returned then the person who gave it back is given a reward which is the knowledge of their race and real past about humans. But their killed right away as we see.
The film ends with the alien UFO taking off from under the pyramid....and because the pyramids are next to the river amazon...when the ship takes off a massive creator is formed and the water fills it up to hide evidence they were ever their.
