Galileo did not discover that the Earth is a sphere; this fact was already known by ancient Greek astronomers. However, Galileo's observations through his telescope, including the phases of Venus and the moons of Jupiter, provided further evidence to support the heliocentric model of the solar system proposed by Copernicus, which implied that Earth was also a sphere.

how can you prove that earth is a sphere by looking at the pole st
It is the Lithosphere.
The Greek philosophers discovered the earth was spherical in the 6th century BC. Parmenides also discovered this in the 5th century BC. In 330 BC Aristotle put for the position based on physical theory and observational evidence.
The ancient Greeks were the first culture to determine that the Earth was a sphere. Philosophers such as Pythagoras and Aristotle provided evidence through observations and reasoning that supported this belief.

A long time ago- around Christopher Columbus's time- people use to think that the Earth was a cube. Scientists now know that the Earth is a sphere. There is also evidence that it is if you don't believe that - but i highly doubt that. Astronauts that have landed on the moon have seen the Earth and have taken photographs of the Earth. They show that the Earth is a sphere. All the planets that the scientists have discovered so far have all been spheres.
Yes, artificial satellites can provide evidence that the Earth is a sphere. Satellites orbiting the Earth take images showing its curved surface, and measurements of the Earth's shape can be made based on satellite data. Additionally, the way satellites maintain their orbits around the Earth is consistent with the Earth's spherical shape.

The largest sphere that can fit around Earth is the geocentric celestial sphere. This imaginary sphere has Earth at its center and encompasses all celestial objects visible in the sky.
Greek philosopher Pythagoras is credited with being one of the first people to suggest that the Earth is a sphere, around 500 BC. However, it was later Greek philosopher Aristotle who provided more evidence for this idea in the 4th century BC.
Ferdinand Magellan was the first person to lead an expedition that circumnavigated the Earth, providing evidence that it was a sphere. Magellan's expedition departed in 1519 and was completed by Juan Sebastián Elcano in 1522.
