Religion and Fear

In class when we discussed Pythagoreans arche "all is number" the point was brought up that definite is good and indefinite is bad. If this is true than we only fear what we do not understand. I thought that this could be relateable to religion. Some people find religion as a response to their fear of the unknown. They create a higher being as an explaination to the indefinite. They are buying in to pythagoreans philosophy.
