Because it was demonstrably the best explanation for the observations that could be made.
Galileo's role model was Copernicus, who pioneered the heliocentric model of the solar system. Galileo was greatly inspired by Copernicus' work and built upon it with his own observations and experiments.
Galileo's work caused controversy because it challenged the accepted geocentric model of the universe, which placed Earth at the center. His support for the heliocentric model, with the sun at the center, contradicted religious teachings of the time. This led to conflicts with the Catholic Church and Galileo being condemned for heresy.
The heliocentric model proposed by Nicolaus Copernicus and further developed by Johannes Kepler and Galileo Galilei is largely accepted today. This model places the Sun at the center of the solar system with the planets, including Earth, orbiting around it.
In the end it was Kepler's model that was accepted as true. Copernicus's model with its circles and epicycles was replaced by Kepler's model with elliptical orbits that were eventually explained by the theory of gravity. The only part of Copernicus's model that has lasted is the idea that the Earth is in orbit round the Sun, which is accepted because Newton's discoveries showed that the Sun is far more massive than all the planets combined.
Galileo did not have his own theory, he was a strong supporter of the Copernican theory, which was a model that contained circles and epicycles, just like Ptolemy's ancient model, but with the Sun at the centre and the Earth in an orbit between the orbits of Venus and Mars. Galileo promoted the theory not only as a scientific theory, which the Vatican supported, but he maintained it was the absolute truth, which got him into trouble. At the same time as Galileo, Kepler brought out the improved model with elliptical orbits, which was generally accepted as the best model many years later.

Galileo is famous for observing and proving his heliocentric model of the universe. After his observation the existing model of the universe was slowly phased out.
Galileo Galilei was forced to admit publicly by the Catholic Church that the Earth stood motionless at the center of the universe in 1633. This was part of the Inquisition's trial against him for supporting the heliocentric model proposed by Copernicus.

Copernicus' heliocentric model provided the framework for Galileo to further explore and confirm through his observations with the telescope. Galileo's discoveries, such as the moons of Jupiter and the phases of Venus, provided empirical evidence in support of the heliocentric model and contributed to its acceptance over the geocentric model.
No the church hated it.
It was not about modelling, it was about reality. Galileo was put in jail for heresy after he continued to say publicly that the Copernican model was the absolute truth, after he had been told by the church that he could use it and teach it only as a model to represent the planets. The model that is now accepted by everyone including the church is the one discovered by Kepler in 1609, which Galileo did not accept at the time because it uses elliptical orbits instead of the perfect circles of the Copernican theory.
A Geocentric model places Earth at the center of the Universe, with all of the stars and planets revolving around it. The most famous such model is that of Ptolemy. It stood as the accepted model until Copernicus was proven right by Galileo and Kepler.
