Faith, Science & Social Justice

I think since there are questions about God and the origin of human being which is addressed mainly by religion, not science, so actually people need faith to find a logical explanation for these kind of questions. However, at the community level faith based believes may divide people and cause troubles, since different people may think differently and believe on their truthfullness based on their faith. I think, at the community level social justice can be ensured through the implementation of the best practices that should come out of scientific experimentation of the evidence.
