Similar to how many of us don't see monks daily in our average society, aliens if they are physically, energetically, mentally evolved, the precision of their decisions to interact or be visible to lifeforms not in their interest will be quite extreme relative to us. So makes sense they will be invisible and beyond contact. <br><br>The mistake of projecting our egos and humanity onto Aliens and assumptions of what interest them and what they would do, is what many of us do to many things beyond our comprehension, creates obstacles for proper insights into the universe.
