Does time exist?

My personal short answer is no, it does not exist. We only remember different states of matter, including ourselves, and we consider it time as a fourth dimension of space. It's like the bidimensional and tridimensional space - we can draw a line or a square on a piece of papre, but the Rubik cube and the sphere are very different that those lines.

The earliest time measurements were observations of cycles of the natural world, using patterns of changes from day to night and season to season to build calendars. We remember pretty a lot of yesterday and we have good memories from last month or last year, but we still can't remember next minute, next hour or tomorrow because that specific state of matter haven't happened yet. More precise time-keeping eventually came along to put time in more convenient boxes, we all use clocks, and may people have been asking themselves what exactly are we measuring?

The video is a lesson done by Andrew Zimmerman Jones, directed by Nice Shoes, in which Andrew Zimmerman Jones contemplates whether time is something that physically exists or is just in our heads.
