At no point during your education will your teacher or professor ever ask you to take anything they say on faith. The reason for this is that in school you're taught what is known, not merely believed, thus there is some method for knowing that information that can be presented to you for your own verification. This is vastly different from religious teachings, which rely on indoctrination and faith-based conviction.
What reasons have we to suspect any gods exist? I will tell you: none. There exists no empirical evidence for such an entity. There exists no sound arguments for such an entity either which explains why virtually all philosophers are non-believers.
So why do people believe? Poor reasoning skills is the most common culprit. However, that's not the only one (and certainly poor reasoning skills are not exclusive to the religious). There are people with sufficient reasoning skills who still believe. These people either compartmentalize in order to preserve the belief (formed prior to their education in logic), or had some experience they truly cannot comprehend which leaves them with an ambivalence. When attempts to reconcile such an experience are made, one often chooses what one sees over what one analyzes. This leaves such a person in a paradoxical state where they wish they could not believe (as a result of being aware that logically-speaking it is naive) but incapable of abandoning such a belief because of the nature of the *divine* experience.
At the end of the day, beliefs are irrelevant. What is important is what is known. It is alarming to me that children are taught religion as factual, as known, when in reality we know better.
