how do you define god? that may shed some light on this matter. if it's something extremely general, maybe i can agree.
Much of our laws of physics are, themselves, on shaky ground. Too often science bases its understanding on theories that have not been proven.
The definition for God http://dictionary.reference.com/browse/god?s=t. Note that there are several definitions in one. Several of these will fit.
I am only a little voice that shows that God exists. Look here: Does God Exist?—Many Absolute Proofs! (Part 1) (https://www.youtube.com/watch?v=FbxD04LWW10).
Are the absolutes of modern science really absolute? Rupert Sheldrake suggests not.

that's the very essence of my point. for the reason that science is unprovable, so is religion, or any substantive sense of "god." if we cannot define what is sitting right in front of our eyes (we cannot---by definition---do so objectively), how can we possible attribute anything to "god?"
that's nonsense. negating science =/= proving the existence of god. it just showcases the limits of our understanding---including the subject of existence.
Are you sure the boss is going to pay you this week? No? Might as well quit right now.
that's a tad dishonest. if we are going to discuss "existence", don't dumb down the complexity of the issue. if we can accept mere observations as truth, then there is absolutely no reason to discuss existence at all. the earth is still flat, etc. etc.---it was observed to be true at some point, yes? thus, to define "subjective perception" as "truth" is inherently wrong. it cannot be verified as objectively true.
in your example, there is a big difference between applying practical knowledge (which is useful but not necessarily true) and establishing universal truth. the question of the existence of god(s) necessarily falls into the latter category, as it attempts to make an objective/universal statement about existence.
sure, we have practical knowledge that the universe is complex---that says nothing about why it is complex, or if that idea even hold meaning at all. complexity, after all, is merely a relative term.
here is an example: say, i write something with a pencil (and you observe me doing so). one could say---as a practical truth---that i wrote something with a pencil. HOWEVER, from a universal perspective, the pencil may not, in fact, exist. and i may, in fact, just be a figment of your imagination. i may not exist at all. so then, to say that "i wrote something with a pencil"---while you may observe this to be true---may be universally false.
subjectivity is a bitch, ain't it? too bad there is no omniscient god to whisper all universal truths in our ears. because even if we thought there was, we would never be able to tell it apart from a hallucination.
