The vast timeless movement theory makes the most sense- there is no time.
An atom moves from point A to point B. So you follow? So then what is time? Time is not even understandable concept because it doesn't exist. You can say "time" is the atom moving between 2 points. Because it has to do so over a "certain time period". How do we record time? How do you even define it? No one can even define time.
