Copernicus's theory has the Sun at the centre but uses a model of circles and epicycles in the same way that the ancient Ptolemaic one used. Kepler continued to use the idea of having the Sun at the centre but, with the help of Tycho Brahe's new accurate observations, Kepler discovered that elliptical orbits allowed a better fit to the observed positions. Tycho instructed Kepler to work on the orbit of Mars, which was a real piece of luck because Mars's orbit is more elliptical than the other planets' orbits (except Mercury). This led Kepler to the idea of the ellipse, which is the model used today.

The phases of Venus are well supported by the heliocentric system, but they are also supported very well by the previous geocentric system. All you need for Venus to have phases is that Venus should pass between Earth and Sun. That happens in both the heliocentric system and the geocentric system.

Galileo's observations with his telescope supported the concept of heliocentricism. He noted that the satellites of Jupiter and Venus, based on their range of phases, did not match geocentricism supported by Ptolemy. He noted that based on these findings, that the Heliocentric theory was correct.
Seventeenth-century astronomer Galileo Galilei.
Aristarchus, an ancient Greek astronomer, thought the sun was at the center. Centuries later Copernicus told his students that orbital trajectories were easier to calculate assuming the sun was the center. In 1610 Galileo observed Jupiter with a home made telescope, and his observations of it and Venus lead him to conclude the sun had to be the center of the solar system. Ten years before Galileo's observations, Giordano Bruno was burned at the stake for his heresy of a heliocentric solar system. But of these folks, Galileo's astronomy was the cleanest, best argued, and had the most supporting evidence.
Nicholas Copernicus is believed to be the first to propose the heliocentric model of the solar system, as it is called. However, the real proof was observed by Galileo Galilei. Using the telescope he greatly improved, he observed that Venus goes through all of the phases, just like the moon. If Venus and the sun were orbiting Earth, that would be impossible.
Nicolaus Copernicus (German: Nikolaus Kopernikus; Italian: Nicolò Copernico; Polish: Mikołaj Kopernik (help·info); in his youth,Niclas Koppernigk;[1] 19 February 1473 - 24 May 1543) was a Renaissance astronomer and the first person to formulate a comprehensive heliocentric cosmology which displaced the Earth from the center of the universe.[2]Copernicus' epochal book, De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), published just before his death in 1543, is often regarded as the starting point of modern astronomy and the defining epiphany that began the scientific revolution. His heliocentric model, with the Sun at the center of the universe, demonstrated that the observed motions of celestial objects can be explained without putting Earth at rest in the center of the universe. His work stimulated further scientific investigations, becoming a landmark in the history of science that is often referred to as the Copernican Revolution.Among the great polymaths of the Renaissance, Copernicus was a mathematician, astronomer, jurist with a doctorate in law,physician, quadrilingual polyglot, classics scholar, translator, artist,[3] Catholic cleric, governor, diplomat and economist.
Pluto was first observed by the astronomer Percival Lowell.
You have it backwards. Theories are supported by evidence. Evidence is not supported by theories, evidence is simply observed.
The heliocentric 'theory' is not really a theory at all, more an assertion that the Sun is at the centre of the solar system. Copernicus's theory assumes that the Sun is at the centre and provides a model of the planets' orbits that uses circles and epicycles to explain the observed orbits. He said it was simpler than the old "geocentric" (Earth centred) Ptolemaic system, but it was not really, it actually had more epicycles. Note: Perhaps the questioner got mixed up. The Copernican theory IS a heliocentric theory. Perhaps the question is about the geocentric theory and the Copernican theory. Anyway, Kepler simplified the heliocentric theory and now we know that his model is correct.
Venus goes through phases similar to those of Earth's moon.
There were two theories concerning the way the solar system was layed out. Back before Nickolas Copernicus presented his heliocentric system (the idea that the sun is in the center of the solar system and all the planets revolve around it) the accepted model was the geocentric system (the idea that the earth is in the center of the solar system and all the planets and the sun revolve around it). Galileo Galilee was a huge advocate of the heliocentric system but the church threatened to expel him if he continued to contradict the system that had existed and accepted for hundreds of years.Obviously, the Copernican system eventually gained total acceptance from the scientific community and recent technologies have been invented that have allowed us to prove that Copernicus was right. So, the answer is because it has been proven and observed by science!
