Time

One time, a friend of mine read an article about the existence of time. Does time really exist? How we know it exists? To me, the time it self is just a measurement of change. As long as thing continue to change. We will measure the time amount for it to change. As long as we acknowledge these changes, we are giving recognition to time. We use time to measure the change within us too. When we are born to our death, there will always be changes made or occur naturally to our body. The usage of time to measure those changes gives time its own very existence.
