There is no need for science and belief in God to come in conflict. For example, practically all biologists believe in evolution. But evolution is just a mechanism for how species arose. But where did the life come from in the first place? If you go back far enough, there is no way to scientifically explain this. Where, for example, did the material that was involved in the Big Bang come from? Once you get back to that level of analysis, it is quite possible to bring God in. Science can answer many questions, but it can't answer things like where the universe came from in the first place.
Albert Einstein once said that science without religion is lame; religion without science if blind. There are many who would argue that the two are in perpetual conflict with each other. This is not so; science, if interpreted correctly, merely complements and explains the teachings of religion. The greatest conflict seems to be over the idea of creation. If the Genesis story of creation is treated symbolically, there can be no conflict. The seven days were not necessarily twenty four hour days; but rather stages of creation. Genesis says that man was created from "the dust of the earth," which can easily be interpreted as his arising from the lowest form. For those who wish, there is no conflict between the two; for those who are convinced that they have all the answers (a dangerous conclusion in any discipline) the conflict is there.
