I think that guy was eating the glue

The reason for 12-hour clocks is most cultures worldwide have variable length hours of over a year. For Western times this comes from Greeks who had 12 day and 12 night hours. Early water clocks in antiquity would attempt to make that adjustment automatically.

How did people refer to clockwise movement before the invention of the clock?

Yes, when you are in the northern hemisphere, a sundial shadow falls to the north of the gnomon (the thing that makes a shadow). This makes the shadow move from the northwest to north to northeast over a day, which is clockwise. In the southern hemisphere, the shadow from the gnomon falls to the south, so it starts in the southwest and moves to the south and then southeast, which is anticlockwise.

The most obvious way to see this is the photo of the sundial in Perth, where the hours run anticlockwise.
