Any small object or point of light following a wind-borne/ballistic/orbital trajectory in the vicinity of Earth can be safely assumed to be man-made.
“UFOs” do things. They dart around and change direction. IOW they demonstrate intelligent control. If you don’t have that happening, then you have a satellite or a balloon.
You don’t see stars in the daylight ISS video of Earth because the Sun is very bright and camera sensors have limited dynamic range.
I probably have a bit of an unfair advantage in evaluating “UFO” videos because I’ve been an electronic tech working with visible and IR video since the 70’s. For both consumer and military applications. Retired since 2017.
maybe it’s Elon space car in orbit still ?

And they can somehow tell if you are looking directly at them or not. They can sense it...
