The difference is, though, that scientists don't agree based on evidence; not mere belief and interpretations of ancient scribblings.
Many scientific theories don't have actual evidence, but there are still supporters of them and those who disagree with them.
Good example is linguistics, although this could be applied even on other branches of science. However as I said many times before, there's no actual point in comparing science and religion since they give different answers to different questions & also they have different roles in human's life.
