Truth^ Consider the vastness of space...making the crossing of these distances impossible.  The whole ET propaganda msg is designed to prevent you from asking the right(obvious) questions. But crazy as it is, selling folks on ET is much easier than making them understand how little they know about the black projects and shocking advances in sci/tech being withheld from the public for “Nat Sec” purposes.  Although, many here don’t want to hear it, ET is bullshit and has been used against you to keep you ignorant. That’s one conspiracy theory you can drop like a bad Star Wars movie.
