That's a perfect example of what I was saying. It was the best information available at the time. Very different thing than "the truth". You have to look at the information that goes into the formation of a hypothosis. Then you have to see if observation bears it out and if it is accurate in it's ability to predict future events.

Of course, it's also ancient. What's wonderful about living today is that there is so much information available it leads to so far more accurate conclusions. We, indeed, have come a long way in the last 2,000 years. Copernicus and Kepler really ushered in the modern age of science. Before that "science" was really as much superstition and religion as science.
