Oh, I have no problems with that. I agree, the early astrologers could only work with the tools they had. And at first the heliocentric theory met with resistance because it was unable to predict the positions of the planets with any more accuracy than the geocentric model. Primarily this was because they still considered the planets to be moving in perfectly spherical orbits, according to divine plan. Then Galileo came along with his telescope, which showed that there were satellites orbiting Jupiter, not Earth, and that Venus showed phases just like the Moon, indicating a heliocentric system. The Church didn't like that idea, though, as it went against dogma that the Earth was the center of the universe. It was only after Kepler deduced that the orbits of the planets were, in fact, ellipses that the heliocentric theory was able to overturn the old geocentric theory. Even then there were detractors, though, who based their opposition on the teachings of the Church. If nothing else, the Church's stranglehold on education seriously delayed the advancement of science and freedom for the common man. That's evil enough for me.
