Put basically, Galileo’s personality, coupled with the fact that his views on this matter were not backed up by observational evidence at the time, led to all sorts of problems.
When certain Churchmen claimed that Galileo’s theories were ridiculous insofar as natural philosophy/science are concerned, they were actually quite right based on the best evidence they had available. When they interpreted Scripture to speak of the earth being the center of the universe, they were actually quite right … again, based on the best scientific evidence they had available, which could not be used to force anything other than a literal interpretation.
Furthermore, Galileo was a prideful and arrogant so-and-so. He used to go around to dinner parties, and stage debates with himself wherein he would take both sides of a position to show off how good he was at making arguments. He did that merely for the sake of entertainment; it was a cheap party trick. Of course he was viewed with suspicion … especially when, once again, there was no hard, observational evidence to support his claims, and when he had a reputation for being full of himself.
Galileo was a genius whom the Pope wrote poems about and who intuited the truth about our solar system. And Edgar Allan Poe was a genius who intuited the Big Bang in* Eureka*. But neither based their ideas on arguments that would today be remotely accepted. Indeed, in the case of Galileo, many of his arguments were manifestly untrue: they could be seen as such then as well as now.
