I sometimes wonder if the universe is not populated with “extreme extremophiles” and the UFO’s we see are just “Space Cattle” that wandered onto our little Pollyanna globe. I know, nuttier than a fruitcake concept.
I once had a dream as a child, about how we lived on a planet that once a day at the same time, if you didn’t grab a hold of something you would float into the air and disappear into space. Everywhere there were grab bars so that you always had something to grab handy.
One time I got caught out away from everything in a field and lost track of time. that time came and I floated away. But just before I met my demise, I saw a giant wielding a vacuum cleaner and realized I had been living on a speck of dust. :)
I remembered this dream when I was older, and realized that there really isn’t much difference between that dream and reality. We live on just a speck of dust in the whole of things.
