Galileo Galilei noted that; if our Earth and other planets went around our Sun, Venus would exhibit phases like our Moon; but if our Sun and other planets went around our Sun, it wouldn't. GG looked at Venus over the course of several weeks and noted unmistakeable phases. He thus concluded that the Copernican model was not just a useful model for calculation, but supported by observation.

How did Copernicus disprove ptolemy's theory about universe?
Copernicus proposed a heliocentric model of the universe, with the Sun at the center and the planets orbiting around it, while Ptolemy's model placed the Earth at the center. By providing a simpler explanation for planetary motion and accurately predicting the positions of celestial bodies, Copernicus's model challenged the complexity of Ptolemy's geocentric theory and gained acceptance over time.
