ELI5: Why are moths attracted to bright lights in the night, yet they never come out in the day?

Does the sun affect the moths? Do they get harmed by UV from the sun? Are there predators during the daytime that harm moths who sleep at night? I want to know the answer.

Most moths are nocturnal, so they don't come out during the day.

They aren't attracted to bright lights. They use the moon for navigation. By keeping the moon in the same place in their view, they can fly in a straight line. They mistake artificial lights for the moon, and in trying to keep the light in the same place, they end up going round it in circles.
