"Believe in" ... no. Stronger that that. I **know** they exist. I've seen two, in person, one in about 1976, the other in 2013. The first was near dusk but it was not dark. I watched it for at least 3-5 minutes. The second was in bright sun, mid morning, probably 100 feet, no obstructions. Zero room for doubt. That's like still questioning whether the earth is round or flat.
