There is more information today about how we only see 20% of what
really out there. This is more dark matter in the universe and visible
matter. Could there be other multi dimensional life forms? Why not?
Just because humans can't see it doesn't mean it is not there.
AFter all, 300 hundred years ago, we could not see microbes that are
alive! So if you asked people back them if dirt was alive, they would
say no!
