Shock of God - Let me address some things for you. Your belief that your God offers a base of objective morality is inherently flawed due to your own doctrine... let me explain.

Premise1 - God is all-knowing. (Job 37:16, Psalm 147:5, 1 Samuel 2:3, Isaiah 55:9, Job 28:24, 1 John 3:19-20, Hebrews 4:13, Isaiah 46:9, Matthew 10:30, Psalm 139:4)

Premise 2 - God created man in his own likeness. (Gen 1:26–27, Gen 5:1–3, Gen 9:6) This means through the substantive theological principles that our deductive reasoning skills are similar to God's, as they are an attribute of His image and we are a likeness of that image.

Premise 3 - Mankind can find reasonable and logical reasons to create detailed codes of law that govern over acts of moral turpitude, and the ability to reason those things out is a similar if not mirror image of God's same ability for reason.

Premise 4 - God commits acts that mankind would find legally reprehensible as crimes of moral turpitude, such as mass child murder and genocide. (Do you really need me to quote all the verses of God's merciless acts of psychotic behavior according to your useless book? You've read it right?)

Conclusion - The God of the bible is less moral than the reasoning of human beings and therefore cannot be a valid source of moral guidance and has in fact refuted His own claim of perfection.

To address your claim of God's objective moral high-ground;
Again, this is a self-refuting argument. As shown in this analogy:
"God is perfect"
"Who says? What do we have to judge that by?"
"God says and you must judge it by God."

Now we're down to the nitty gritty... the hubris of religion and the dementedly religious like yourself that are the objects of my disdain and general anger. Your claim that there is no "purpose" without God is the war cry of the coward. You have to have some goal beyond this life to be looking forward to, or you'd just curl up and wait to die. There is so much "purpose" to life without God that your tiny little mind just can't even fathom it. That's the real problem with all you "I've got an axe to grind with those immoral and purposeless atheists" types... you just can't see living without a carrot to chase so you do your best to make it seem as if all of humanities problems rest on the shoulders of someone else. It's the immoral atheists and the immoral homosexuals and anyone but yourselves that are the reason you're not happy enough in this life and have to spend your life on your knees begging for one where you don't actually have to work for it.

So let me give you some advice, okay - Grow up. Man up. Stop blaming everyone for shit and making idiotic statements like your atheists lack morality crap. If you truly believed or had "faith" in your God then you wouldn't be here trying to defend Him and if He were real then he could defend Himself.

Now let me end this by going all the way back to the damn OP and remind you that you DIDN'T meet the criteria given of VERIFIABLE and PROVABLE evidence and in point of fact have given nothing but utter contrivance and personal opinion. I was specific, so either you purposefully ignored that, or you're even more dense than I've come to suspect you are. Now if you can't present what I asked for, then you're pissing up a rope here and may as well move along.
