I wasn't really calling atheism or science a religion as much my point was about the lack of absolute certainty that unavoidably leads to you relying on faith.

Atheist believe that there is no god but they can't prove it, the same way Christian can't prove that God exist, so both groups ultimately relay on faith.

As far as diabetes go it wasn't really the maybe point of the post. There is another theory out there "proven" by science that diabetes is caused by intramuscular fat. How do you ultimately know which one of the theories is true?
