Depending where you fix your point of reference, you determine the direction of the rotation of the Earth. If you take the North Pole as your reference point, then the Earth rotates counter clock wise around its own axis. If you take the South Pole as your reference point then the Earth rotates clock wise. In addition all the planets rotate counter clock wise around its own axis and the sun appears to rise from the east, with the exception of Venus and Uranus. Although all planets revolve around the sun counter clock wise, Venus and Uranus rotate around its own axis clock wise and the son therefore rises from the west on these two planets. Pluto also rotates clock wise around its own axis, but since it is no longer a planet, it has been accordingly neglected. If you ask why the planet Venus rotates clock wise unlike the other planets, then there must be a reason. There are many theories explaining why Venus rotates clock wise around its own axis: One theory explains this phenomenon as a result of a big meteor that struck the planet and resulted in changing its direction of rotation. There are other theories that deals with gravity being the cause of this change and has resulted in shifting the planet's rotation in the past slowly until it stopped and started rotation clock wise. The final understanding why is this has not been determined by Astronomers.

Whoever decided that the North pole was the top is the reason. Its a matter where you are observing from. People standing near the South pole would appear to be rotating in the clockwise direction

Luck, and only luck. When our solar system was forming, it was basically a big disc spinning anticlockwise. So when stuff coalesced into planets, they were spinning the same direction as the original disc of dust had been.

There are solar systems that spin clockwise, for what that's worth.

This happens because the earth is pulled around the sun in an anti-clockwise direction. The resultant centripetal force causes rotation in that direction.

Look at it "upside down" and then it is.

We chose "north" as "north" because most of the map-makers were in the northern hemisphere, and it made sense to them to call it "up".

If civilization and map-making started in South American or Australia, then Antarctica would be at the "top" of the world. It's just a convention that someone chose a thousand years ago.

Depends which way up you are in space.
Theres no north or south out there so clearly no clock / anti-clockwise.
