and it is rational to believe the premises

I just can't think of any premise I could rationally believe that involves the supernatural (the invisible, unmeasurable, intangible, etc.)...

I take the existence of God to be what's known as a basic belief which supports all other beliefs, and that without that basic belief we are unable to rationally believe anything. I thus reason from God's existence, not to it. [This means that I take a particular epistemological view called foundationalism, which says that a belief is rational if it is basic or it is ultimately supported by at least one basic belief.]

Basic beliefs are said to be self-justifying or self-evident

Typically and historically, foundationalists have held either that basic beliefs are justified by mental events or states, such as experiences, that do not constitute beliefs (these are called non-doxastic mental states), or that they simply are not the type of thing that can be (or needs to be) justified.

A foundationalist might offer the following theory of justification:
A belief is epistemically justified only if (1) it is justified by a basic belief or beliefs, or (2) it is justified by a chain of beliefs that is supported by a basic belief or beliefs, and on which all the others are ultimately based.

Well, I can definitely see how you might believe in God if this is where you're coming from. However, I personally don't see God as self-evident at all. The world makes much more sense to me as an atheist than when I ever believed in God (and I did, for a while). I think we can rationally believe things and have rich emotional experiences because we have amazingly evolved brains. Some may call their experiences 'God,' but I just don't see the need.
