Myths cannot be quantified, replicated or calibrated. Religion does not require a test for truth, only the faith that a belief is true. When a theologian makes a statement, it is taken to be true by those who have faith in that theologian and rejected by those who do not. There is no way to know what is true and what is not. The danger from religion is that any statement can be taken as true.
Science requires verifiable, repeatable observations.
When a scientist proposes an explanation, the scientist must provide proof that others can consistently duplicate with identical results. This is reality and knowledge of reality is not dangerous, but enlightening. Although this knowledge can produce dangerous results, science also provides the means to harness knowledge so that it can be beneficial. Knowledge that led to the atom bomb has also led to cures for cancer and the understanding of the fundamental structure of the universe. Scientific knowledge has produced technology that has allowed humans to pollute our planet, but science has also given us the knowledge to stop the pollution and the technology to accomplish it.
