Through his observation Galileo watched the motions of the planets and the sun. Using triginometry and geometry, he flat out knew that the earth could not be a stationary body. He also knew that the Earth could not be the center of the universe. The math told him otherwise. This was in direction contridiction of church doctrine and more in line with the helocentric theory that Copernicus came up with.
Also the phases of Venus that he observed could only be possible if the Earth and other planets revolved around the Sun.He also discovered 4 of Jupiter's moons. This showed that there were objects revolving around other planets and not everything revolved around the earth
Using the new technology of the telescope, Galileo discovered the moons of Jupiter: Io, Europa, Calisto, and Ganymede, thus proving that not all things orbit around the Earth,

Nicolaus Copernicus -> Galileo Galilei
Aristotle said the earth was in the center. Ptolemy supported Aristotle and added to it. Copernicus said the sun was in the middle. Galileo also said the sun was in the center and added to Copernicus.
A lot of people, Copernicus, Galileo, Einstein, Stephen Hawking, Hubble etc.
Galileo Galilei was the Italian mathematician and astronomer who was forbidden by the authorities to teach his ideas. His support for the heliocentric model proposed by Copernicus, which stated that the Earth revolved around the Sun, was deemed heretical by the Catholic Church. Galileo's works were placed on the Index of Forbidden Books and he was placed under house arrest for the remainder of his life.
