Hi Abogot,
This has only one inherent problem - you have to define what to "exist" means and you can't use science for that. Your only hope is philosophy but no matter how much stuff you read, there is no clear cut answer at all.
The only reason
existance is an issue that goes beyond science, is because we humans feel that it goes beyond science. It does not. Philosophical musings about existance, while fun and challenging to the mind, are supported by nothing more than subjective intuitions. That is not anything we can base a good theory, or even hypothesis, around.
But even if imagine there were such an explanation, you still have not provided information where god does not exist -
The first question should be, Are humans right in thinking there is a God?
We are the only species, out of billions that have existed, that display a need to search for this 'God". Now it is either a made up, imaginative being that exist only in our minds(those minds which choose to accept it), or, God really does exist and we as humans have been endowed with the ability to search for him/her/it/charlie the unicorn.
Using all of our
current ability*, God is non-existant by objective standards.
*I meant 'current ability' because I've never been able to rule out evoluton as the mechanism for higher consciousness and thus, PERHAPS, a new level of awareness that may begin to reveal God in our surroundings. I am an atheist, because of our current knowledge, but I can't seem to be able to rule this one out.
If being light sensitive lead to sight, and consciousness has lead to theories about the science and nature of our universe and our origins, perhaps if our consciousness continues to evolve as our brain evolves, then deeper meanings about existance, God, etc, may be found. But with our
current ability we can
only determine that God does not exist objectively.
