Wow thanks a lot Hive account@xylu , and you're welcome! If that kind of subject interresses you, know that I'll be talking a lot here about great unsolved mysteries like that! Next one will probably be about the Nazca line, very interresting matter as well :) And don't hesitate to check out my previou post about J.F Kennedy's death, I wrote it all by myself! See you soon on steemit.
