Ah, but Galileo didn't bring about the scientific revolution single-handedly, did he? He was just one of a number of people. He did a lot of important work applying the scientific method to astronomy and physics, but he hardly invented the method in the first place. If it's the method that you think is so important, you should be praising Roger Bacon, or indeed Aristotle himself, not Galileo. See the discussion we're having in the thread on monotheism... Also, I don't see that he completely overthrew Aristotelianism. There were plenty of Aristotelians for a long time, and in some spheres, such as ethics, Aristotelianism has come back in a big way in more recent years. As far as science goes, it was really Descartes and (much more) Newton who exorcised the shade of the Stagyrite.
Besides which, of course, Galileo got a lot of things wrong. He thought he could prove heliocentrism definitively by his theory of the tides (he said the tides must be caused by the earth whirling about, making the seas slosh backwards and forwards), which was obviously wrong. More importantly, he believed that scientific theories are accounts of how things actually are, rather than models to predict phenomena. Strikingly, the church in Galileo's day held the latter position, which was exactly the same as most modern scientists.
