does time exsist?

there can never be a present becuase as soon as you say such, it is already the future and now when you said thatm it was the past.

The present is right NOW... but the moment has already expired.. becuase of how you measure time... seconds and be cut down and mili-seconds can be, and so on and so forth... so it's like an infinate, and since there is no end point on an infinate then how can there be a present... time exsists only in our heads, like this writing it is only thought.

There are probably a lot of things wrong with what I have said, but I'm curious to hear them.
