Red Orb
Another explanation for mysterious lights in the sky is fireworks. Since they move so fast and light up the sky, it’s pretty easy to mistake these things for craft from other planets. Especially around the fourth of July, when people set fireworks off all the time, you’re likely to see “UFOs.”
At least this Reddit user was rational enough to recognize that this could be an explanation. Maybe someone accidentally set off this last firework, or maybe it was one that took a short while to go off. But you’d think that this individual would’ve at least heard a banging sound.
