Answer 1

Imagine a fly and a person both moving at normal walking speed, the fly traverses its own width100 times in a second, you can barely perceive it being in a single place, so much so that it’s almost impossible to see it at all. but the person traverses its own width maybe 2-3 times a second, if you look at them, likely they are going to be roughly the same place after a second.
