Galileo showed facts" - but was nearly burned at the stake beacuse it was alleged it contradicted the bible
The real debate was between Aristotlean and Copernican astrology and the real problem lay with Galileo proclaiming Copernican astrology to be truth without sufficient evidence.
He even published a book in the vernacular stating that it was truth. Now books in the vernacular weren't for the learned, but the common masses. It's like coming up with a new scientific hypothesis without even submitting it for peer review (all of which was done in Latin).
You have to remember, there were people, scientists even, who didn't like Copernican astrology. It just happened that these were in the Inquisition.
But Galileo did have some friends, like the Pope (Urban, not the one before) and St. Robert Bellarmine (a powerful cardinal) who said:
"I say that if a real proof be found that the sun is fixed and does not revolve round the earth, but the earth round the sun, then it will be necessary, very carefully, to proceed to the explanation of the passages of Scripture which appear to be contrary, and we should rather say that we have misunderstood these than pronounce that to be false which is demonstrated."
