Or how about this:

Ball lightning is something that many people claim to have seen and, yes, it moves slowly or not at all which admittedly doesn't fit your description.
A very interesting phenomenon too, and one which has yet to receive a convincing explanation.

Re: Do extra terrestrials exist.
During the 1990's, there were thought to be 200 billion galaxies in the universe. Today it is thought that the number of galaxies exceeds 2 trillion galaxies. So, how many planets per galaxy ? An estimated 50 billion/galaxy. How many planets in total in the entire universe ? 50 billion X 2 trillion . Good heavens, that's 50 X2 X billion X trillion.Personally, I am quite certain that the universe is over-flowing with life. Everything from bacteria to ultra-advanced life. I agreed with Carl Sagan when he said that there are more STARS in the universe than there are grains of sand on all the beaches of earth.
Have aliens ever been here ? I seriously doubt it but if there is no other intelligent, sentient life in the universe , then that is one heck of a lot of wasted space.

A fun thing to think about is that our radio signals have been reaching Alpha Centauri beginning 4.65 years AFTER our 1st radio broadcasts. What would THEY think about US based on our music ?

Re: Do extra terrestrials exist.
I remember watching Brian Cox talking about life on other planets he said he was sure it existed but to find other life like ours here on earth he was sure that would not exist. He said we evolved from a series of genetic accidents that would be impossible to emulate.11-01-2021, 10:53 AM

There will also be a range of 'levels' of life, from microbes to beings which far exceed our development, intelligence and abilities.
I wonder whether we'll ever actually 'make contact' with any of them.
