In what ways is science different from belief system such as religious faith?

Superstitious Beliefs have no basis in reality and no evidence to support them. They are passed though the generations by people and have never been confirmed or found to be true. The human brain is prone to delve into the absurd.

Scientific beliefs are theories and hypothesizes based on the accumulation of evidence.

beliefs that arn't based on evidence should not be believed at all.

Germ Theory=scientific belief

God=Superstitious belief
