Because they are naturally occurring magnets / compasses (i.e. can indicate magnetic north).
Natives taught early explorers survival skills, navigation methods, local geography, and sustainable practices for living off the land. They also shared knowledge about medicinal plants, food sources, and cultural traditions, which greatly influenced the explorers' understanding of the new territories they encountered.
Amerigo Vespucci used navigational technology such as the astrolabe and the compass, along with maps and charts, to aid his voyages in the late 15th and early 16th centuries. These tools helped him navigate across the Atlantic Ocean and explore the coast of South America.
Jacques Cartier utilized navigation tools such as the astrolabe and quadrant, along with maps and compasses, during his explorations in the early 16th century. These tools helped him determine his position at sea and navigate unknown waters, making it possible for him to map out new territories like parts of Canada.
The first people to use paper money were the Chinese during the Tang Dynasty in the 7th century. The government issued the world's first official paper money to reduce the need to carry heavy metal coins.
People in the Stone Age primarily traveled by walking. They would often follow animal migration patterns, travel along rivers, or use natural landmarks as navigation guides. Some evidence suggests that early humans may have also used boats or rafts to travel across bodies of water.
Chinese sailors used a lodestone as a compass for navigation because lodestones are naturally magnetized stones that can align themselves with the Earth's magnetic field. This property allowed them to determine the direction they were traveling in, aiding in their exploration and trade expeditions.
The Chinese were the first to use a compass for navigation, dating back to as early as the 2nd century BC.
The Chinese were likely the first to use magnetic rocks, called lodestones, to navigate at sea around 1000 AD. However, the first documented use of magnetic rocks for navigation was by the Europeans, specifically by the Italian explorer Flavio Gioia in the early 14th century.
China is credited with making the first artificial magnet around 2,000 years ago. Through the use of lodestones, which are naturally magnetic rocks, the Chinese were able to create these early forms of artificial magnets.
The use of magnets dates back over 2,000 years, with natural magnets known as lodestones found in ancient civilizations like China, Greece, and the Middle East. The first artificial magnets were created by the Chinese around 1000 BC by heating iron ore. Today, magnets are widely used in various technologies and applications.
Human navigation of the stars dates back thousands of years, with evidence of early star maps and celestial navigation tools found in ancient cultures such as the Babylonians, Egyptians, and Greeks. The use of stars for navigation allowed early civilizations to travel long distances by land and sea.
The invention of the compass is attributed to the Chinese, who developed an early version using a lodestone around the 11th century. The compass was then further improved by the Europeans for use in navigation during the Age of Exploration.

No country invented the magnet. Magnets are naturally occurring objects. The Chinese were the first to use a magnet as an aid to navigation.
They used a combination of practices. Prior to the early 1700s, captains on sailing ships used the stars. In the 1600s, they used "Reflecting instruments". By 1730, they used a sextant which is a "doubly reflecting navigation instrument". All instruments used angles between stars visible to the ship. The compass was in use as early as the ChineseHan Dynasty (about 206 BC). It was used for navigation by the Song Dynasty Chinese during the 11th century,
