Look up. Day as much or more than night. In the city or country. Look for what looks like a star when driving on the highway while dark but is way to low and moves slowly. In the day the are only visible when they move or light up or are active if you will. They and are very bright. A photo looks like an energy sphere.
Look up. Ignore spray drones that reflect the sun. Look at the sky in movies or tv shows. Look at the sky in photographs. If you want proof simply look. They can be right above a highway looking like a star but you get closer as you drive. People don't see spray trails do they are out in the open a lot.
