my thoughts--most people have already decided whether they believe God exists emotionally, discussions like this are only a matter of reinforcing that decision in their rational mind. high rational intelligence can easily lead to pride, or believing that because we know relatively more than other humans that we know everything. it is this rejection of the notion that we aren't to be omniscient or omnipotent that causes us to close our minds to other perspectives or information, true or false as it may be... we desire to know everything, it follows that that is what we would tell ourselves. however, if we hypothetically consider the existence of an omniscient and omnipresent being, wouldn't our place, as limited in our knowledge and abilities, be below such a being? and yet, we discuss the existence or lack thereof with other humans, our equals, so that such a thing can be considered comfortably in a way we can control and understand. it's foolish to think the thoughts of you or I are anything but entirely inconsequential to reality, truth, the existince or non-existence of an omni-being. that is why approaching the issue from an entirely rational standpoint will come up short, with nothing to say conclusively one way or another. im aware this is a difficult suggestion to swallow, to accept our limitations.
let's say we are detectives arriving at the scene of a murder... do we have to know the perpatrator's hair color, the model of the firearm, the exact time of arrival to say whether the body in the middle of the floor means someone was killed? if we put aside our personal desires, whether they are for God to exist or not, wouldnt the aftereffects still remain in the present without a need for empirical proof of how? perhaps we are looking in the wrong place... yes, the creation of earth and space, fossils and how life developed, and modern physics can explain portions of the details of how we are, but this is a binary question, a question of the obvious, and the answer should be equally so obvious.
so why is it not so obvious to us? this is why it is a question of emotion, of human nature and our motives first before it is a question to be approached rationally. for us to ask "is there a God?" is presumptuous to such an extent that only humans could be, it would be more enlightening to ask what we are doing now and why. so to answer the question of whether God exists, i have instead another question: why do you think you want to know? because that is one that would all have the answer to.
