The very essence of science leds to knowledge and understanding. If a scientist errs and produces an incorrect conclusion, science has a built in mechanism for discovering errors. The scientific method provides an orderly and verifiable process for determining what is reality. It is true that when humanity learns how to use this knowledge, it can be utilized in a way that is dangerous. To claim that science is dangerous because the knowledge it produces may be dangerous is like claiming an apple tree is dangerous because someone picking apples may fall out of the tree.
Religion espouses mythology, mainly concentrating on the prevailing mythologies of the day.
These are legends embodying faith in the supernatural. 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.
