In my way of thinking it is statistically impossible for there to be aliens who just right now show up to interact with us. They had 3 billion years to show their presence and just right now , not before, not later, they arrive. It is too unlikely to believe.
As Garry Nolan (head of Pathology at Stanford Univ Medical School IIRC) says, "they've been here all along."
I just found the above-linked article on Garry Nolan and his positions on this subject...will post it shortly.
There have been sighting for many years, including famous one over Washington D.C. in the early 1950s. Sightings during World War II (pilots called them “foo fighters”).
Maybe they are us from the future. Hmmm....
Ancient alien tv series...
Maybe they can time travel and they're here (ie, here-now) to see the Big Event...whatever that may be.
Also, they could have been here a billion years ago, and a million years ago, but nobody on earth made a diary entry about it.
I used to think the same way a couple of years ago.
Now I wouldn’t be surprised at all of a UFO landed in my front yd.
