His observation that something (Jupiter's moons) clearly and unambiguously orbited something other than the Earth was a stinging rebuke of the geocentric theory. In and of itself, it didn't prove that the heliocentric theory was right or wrong, it just proved that some things didn't orbit the Earth which paved the way for asking if anything really did orbit the Earth (the Moon does; other than that, no).
Galileo supported Copernicus's heliocentric theory
Heliocentric theory
He made no discoveries that directly support the heliocentric theory, but his discovery of the moons of Jupiter, circling Jupiter and not the Earth, opened the way to questions about what else might not be orbiting the Earth, like the Sun, for example. Some one hundred years after Galileo's time it was found that the Sun is in fact at the centre, but in Galileo's time science did not possess the knowledge to settle that question.
He was an Italian scientist of the 17th century. He did not prove the heliocentric theory. But everyone accepts the heliocentric principle now, after it was proved right; but that happened long after Galileo's time, after new scientific discoveries in the latter half of the 1600s.
Galileo made important discoveries in dynamics but he contributed little to the debate about the geocentric and heliocentric theories. His quarrel with the church caused a polarisation that was seized on by the reformed protestant church which liked to claim that the catholics were opposed to the truth. But the heliocentric theory was not shown to be the right one until about 100 years after Galileo's time.

Galileo Galilei . He only helped support the theory through his observations , he didn't invent the model, Copernicus did.

None, but Galileo's discoveries demonstrated faults with the old Ptolemaic system. These faults were removed in Tycho Brahe's model, which was also geocentric. However the heliocentric theory of Kepler, using elliptical orbits for the planets, was eventually accepted by everyone, but that happened many years after Galileo's lifetime.
Galileo's discoveries showed faults with the old Ptolemaic theory, which had the Sun at the centre. So he was right to publicise these but not to proclaim that the heliocentric theory of Copernicus was correct. Tycho produced a geocentric theory that explained the phenomena discovered by Galileo, which were (mainly) the full range of phases dislplayed by Venus. Eventually Johannes Kepler brought out a new heliocentric theory with novel elliptical orbits for the planets. It was later backed up by Newton's theoretical discoveries and by later measurements, and it is the model used and accepted today.
The heliocentric Copernican theory that the earth and other planets revolve around the sun in a circular motion
That is the heliocentric theory.That is the heliocentric theory.That is the heliocentric theory.That is the heliocentric theory.
Galileo did not propose a heliocentric theory, he agreed with Copernicus and his heliocentric theory. The Catholic church, at the time, disagreed and they held a huge amount of power and put him on trial.
