Its why they call it faith, bro.

Yes, though keep in mind that a proper definition of faith, is more akin to trust (vs 'wishful thinking' as it is sometimes portrayed).
for trust to make any sense you have to be certain the thing is there to begin with. that's why people usually mean "wishful thinking" when it comes to religion, because it involves the element of uncertainty.
like when you tell someone a secret, you know for sure they know it and you trust them that they'll keep it safe. if someone breaks into your house and you're not sure if they read your diary, you _hope_ and wish they didn't, you don't **trust** they didn't.
the certainty is the difference. believers claim to have that certainty (which is why they insist on the "trust" meaning), while us nonbelievers maintain that you can't be certain, thus "faith" can only mean "hope".
sure you can trust the burglar didn't read your diary... but you might be wrong and it has nothing to do with your trust being broken, it has to do with your assumptions being wrong.
The thing is, I am as certain as one can be (excluding alternate reality stuff like the Matrix, or non-reality type Eastern religions).
First, I have had what is, to me, a convincing supernatural experience (it was highly personal, so I won't go into detail... though it was shared/confirmed by another person, so not just some kind of hallucination). I obviously don't expect you to place much weight on such a thing... outside whatever weight you'd apply to such testimony.
Second, the evidence is such that I see no way for there to be no creator god. The question then becomes, which religious view is the correct one, if any.
This is where the faith/trust step comes in. The God of the Bible and revelation of nature/character via Jesus, is convincing to me that this God is worthy of trust and worship. It is possible for me to be in error on that point, because a being that powerful, would have the capacity to deceive me (if that is possible to coincide with the nature of such a being).
But, doing otherwise would be bit like not trusting your spouse. I suppose they could be a serial killer who has been tricking you for decades. But, as you know them deeply in every possible way, your trust/faith that this is not the case, becomes well justified.
