Summarize this article for a 10 years old
In many countries, kilometre zero (also written km 0) or similar terms in other languages (also known as zero mile marker, zero milepost, control stations or control points) denote a particular location (usually in the nation's capital city) from which distances are traditionally measured and some use this as their official country location or coordinates for faster search at space satellites, this is also used for measuring distances between different countries around the world. Historically, they were markers where drivers could set their odometers to follow the directions in early roaming guide books.
