Well, science is not religion and it doesn't just come down to faith. Although it has many of religion's virtues, it has none of its vices. Science is based upon verifiable evidence. Religious faith not only lacks evidence, its independence from evidence is its pride and joy, shouted from the rooftops.
Religion, is based on belief. The belief that there is a higher power that has created everything and governs everything. Science is not based on belief. That said, more theoretical and therefore less empirical evidence based fields of science (formal sciences) can include believing in the possibility of something.
