It stops at the poles because on the other side of the planet Zero longtitude,or GMT, runs from north pole to south pole.
The truth is, we don't know. We have evidence of about two to three thousand years of residence in the area of northern South America and Central America. Most of this is monolithic ruins, and most of that represents the latter half of that time. But, there are sites in lower South America that may date back as far as 170,000 years from the present. There are sights in North America that date from around that time as well. So, it is a fair bet that there were people in the space in between, Amazonia. Most archeologists don't accept the possibility that man existed on the Western Hemisphere that far back, and some doubt the existence of modern man then. The evidence exists, however, and the dating and relics are being sorted out and discussed.
A major impact of humans in the environment was the extermination of the North American megafauna by humans arriving on the continent some 14,000 years before the present date.

No. It has two ends, at the north and south poles.
No, the Prime Meridian ends at 90° north and south, it then becomes the International Date Line.
The distance is zero. The north pole is one end of the International Dateline. The south pole is the other end.
They intersect only at the north and south poles.
Through the Pacific Ocean, and between the north pole and the south pole.
You're thinking of the International Date Line and the Prime Meridian.

The International Date Line
The International Date Line
Lines of longitude or meridians The Prime Meridian is on one side of the Earth, and the International Date Line on the other side.
The International Date Line marks the location where a new day begins. It runs from the north pole to the south pole.
North America, South America, roughly half of Antarctica, and narrow slivers of Europe and Africa all have west longitudes, i.e. are east of the International Date Line.
