Time, does it actually exist?

Time is so simple, and so very small and minor in our lives. Time...all it means is that things move. Since things move, events occur, meaning that one will occur after the next. Time is simply a form of measurement with a standard of seconds measuring the space between when things happen and when things need to happen. (like when you need to go to the store at like 7 or so.) So its like an invisible ruler. Whoa, that still makes no sense. Have fun getting a good answer to our question...
