@TheClark: Well put, I have to agree with everything you've said up to this point: "Declaring the non-existence of god or gods is just someone blowing it out their ass - not someone speaking as a scientist."
It all depends on what you mean with god.
As you surely know, you can't prove that something doesn't exist. But sometime the existence of something is so unlikely that we might as well say it doesn't exist. This category would include things like the Loch Ness monster, fairies, zeus, mars (the god), allah, the christian god, invisible pink unicorns and the flying spaghetti monster.
If of course you want to define god as love or the awe and beauty and working of the universe (sort like Einstein) or even just call the cause of the big bang god then fine, that god would by definition exist.
But as soon as you give god human characteristics (good, vindictive, just) and/or mystical powers like being able to read minds (=hear prayers), punish and reward people and so then expect that god to be dismissed as quickly as any of the other mythological gods creatures.
