"More UFO Mythology and Backward Engineering crashed UFO's"

One of my favorite UFO stories involves JFK and Marlyn Monroe in 1962, as it goes: When JFK lost interest in MM and stopped calling/seeing her, she "allegedly" called the national news media and threatened to share her story that JFK "allegedly told her in her ear supposedly during intimate moments where she said that she was going to "blow the whistle"  and tell everybody in America about the little munchkins from outer space that are kept in preservative storage out in the desert. (near area 51!)  Sadly and interestingly, she was found dead just a few weeks later in what was characterized as an accidental overdose of sleeping pills.  Many have speculated that the CIA was involved to keep her quiet!  Are we backward engineering crashed UFO's?  Many speculate and claim to have seen multiple crashed UFO's in test sites near the Area 51 test sites being ?backward" engineered.  Some have even speculated that UFO's have been given on purpose to allow scientists to learn the sophisticated technologies by benevolent factions of the many Visitors.  These ideologies are certainly interesting and are tantalizing food for though.  What do you think?
