We know they are mysterious glowing orbs that appear in the desert outside the West Texas town of Marfa, a phenomenon that has mystified people for generations. According to eyewitnesses, the Marfa Lights appear to be roughly the size of basketballs and are varyingly described as white, blue, yellow, red or other colors. Reportedly, the Marfa Lights hover, merge, twinkle, split into two, flicker, float up into the air or dart quickly. So what are these mysterious lites.. alien or man made?
As the first sighting was in 1883 - we can safely say, not man made Whether the whole thing has been exploited today ……… probably
The town is probably gaining some revenue from them, as they are quite famous. I've never seen them, but I suspect they are a natural phenomenon of some sort. The Wikipedia article cites the findings of a couple of groups of researchers which suggests they are car lights from US Highway 67 or, prior to that, the lights from campfires, but that doesn't seem (to me, at least) to explain the colorations and other phenomenon that have been reported over the years. The US highway probably wasn't there in the 1880s, although there may have been campfires.
It is interesting that these lights seem to show up in many other places, too, and some have been seen for many hundreds of years, according to some of the native legends. Even though it has been studied, there are apparently no satisfactory explanation for why ANY of the mysterious lights are there. I think that this is another of the mysteries of this world that we can’t understand, and so we make up reasons for them. many of the lights are observed close to railroad tracks, and in areas where there have been bad train wrecks, so the people living in the area think that the lights are ghosts of the people killed in the train wreck. If that were so, then it seems like we would have a lot more places where lights are seen, because there have been many rain wrecks, and in places where we do not see lights. Here is an interesting article that tells about some of the other mystery lights that we have here in the United States, and other countries also have the same kind of legends and sightings. https://www.legendsofamerica.com/americas-mystery-lights/
