It seems that when anyone talks about this topic it is done in such a way so as to create fear and sensationalism.
Why not that is what sells.
Here is my angle on this complex puzzle.

It does not matter.

If you some how should happen to ever come into contact with such a being you respect it.
You do what the apostle John did in the book of Revelation and you prostrate yourself before it.
Such a being would never correct such a gracious act shown to it.

Just don't offend it by offering your hand in peace with a handshake.

Where they come from that is a form of worship.

Nanoo-Nanoo!
