Ladies and gentlemen, I present to you a theory based on careful observations and mathematical calculations. The Sun, not the Earth, is at the center of our celestial system. To support my claim, consider the phases of Venus: my telescope observations have shown that Venus goes through a complete set of phases, much like our Moon. This observation can only be explained if Venus orbits the Sun, not the Earth. Furthermore, tracking the movement of Jupiter's moons through my telescope provides strong evidence that celestial bodies indeed revolve around objects other than Earth. I urge you to consider these findings, as they provide a strong foundation for a heliocentric model of the universe.
Imagine you are Galileo Galilei defending your heliocentric theory. How would you persuade the people who believe in the geocentric model?
