Actually, science and religion are often not in conflict. Theologians don't care much about the tensile strength of steel when they have church buildings built. Scientists are generally not particularly interested in the functions of a soul. However, science and religion overlap on some topics. Each then generally puts forth conflicting beliefs on the same topic. The results of these conflicts can often strain the culture. cause needless suffering. and even generate loss of life.
Typical conflicts:
An early conflict:
Perhaps the earliest known conflict between science and religion occurred in ancient Babylon in what is present-day Iraq. The priests had taught that lunar eclipses were caused by the restlessness of the gods. They were considered evil omens that were directed against -- and threatened the lives of -- their kings. Then, local astronomers discovered the 18 year and 11.3 day (223 synodic month) interval between lunar eclipses. This suggested that the eclipses had natural cause. The discovery did not affect the superstitious beliefs of the priests; they still regarded eclipses as a time of great danger to their kings. However, armed with an accurate prediction of the next eclipse, they were able to substitute a temporary king during the interval around the eclipse, thus giving protection to the real king. The substitute was killed afterwards, so that omen was always fulfilled.
A famous conflict:
Perhaps the most famous conflict was between Galileo Galilei (1564-1642) and the Roman Catholic Church, largely over the movements within the solar system. At the time:
The Church interpreted the Bible as teaching the geocentric system in which the Earth is at the center of the universe. The Sun, Moon, other planets and stars revolve around the Earth.
Some scientists taught the Tychonic System in which the Earth is at the center of the universe; the Sun and Moon revolve around the Earth; The other five planets
