People have known the earth is round for over 2,000 years and did experiments. very is likely the Egyptians and Moses thought it was round. most people like flat earthers dont know people knew the earth was round before Columbus.
Humans first realized that the Earth is round through observations of the changing positions of celestial objects in the sky and by observing the curved shape of the Earth's shadow during a lunar eclipse. Ancient Greek philosophers, such as Pythagoras and Aristotle, also provided theoretical explanations for a round Earth based on their observations and mathematical reasoning.
Although nobody knows for sure who first made the discovery that the earth is round, Pythagoras is indeed regarded as being the first recorded person to make the claim that the earth is round.

Although Ferdinand Magellan's expedition was the first circumnavigation of the Earth, many ancient scholars were already aware that the Earth was round. The Greek scientist Eratosthenes was the first to calculate the Earth's circumference, thus proving the Earth's roundness.
Because of gravity. Gravity is a force that pulls everything towards the center of the Earth. This force keeps people on the ground even though the Earth is round. Hope this helps!
