There are no aliens , period.
If there were aliens they would show themselves years ago and not conspirate behind people back with government. Would i want to know any aliens like that? fuk no. A specie that evolved to travel freely in outer space would PROBABLY atleast fix their own problems and not be corrupt.
This is just fire and mirrors, and if there will be spaceships or smth it's gunna be holograph from the star wars program.
