Read this and make up your own mind. Time is a controversial subject in physics and nothing is settled here except the amount of misconceptions among the general populace.
If different species experience time differently to us, (for example flies), does time truly exist, and if so what is it's purpose?
Time is the relationship of things that change.
The Physics (Greek: Φυσικὴ ἀκρόασις Phusike akroasis; Latin: Physica, or Physicae Auscultationes, meaning "lectures on nature") of Aristotle is one of the foundational books of Western science and philosophy.
Physics
deals with the nature of physical reality.
Aristotle also wrote The Metaphysics (Meta is Greek for "beyond.")
Maybe Aristotle thought that just knowing "physics" wasn't enough.
(And it helps considerably if you are familiar with both concepts---at least if you want to say something meaningful.)
Past, Present, and Future all coincide.
Its the human condition that seperates.
Dear Pea Nuts,
No, time does not truly exist, time is completely relative no independent existence, we invented it.

And one of those great theoretical physicists said the purpose of time is to keep everything from happening all at once.
