Firstly, you miss the point. You equated lack of proof in God with a lack of proof in the existence of love and morality. But they are not equitable. You make claims for God's nature that you do not make for the nature of love and morals. Maybe feelings was not the right word. They are immaterial concepts. But you say God actually exists. He has attributes, intelligence. You c;laim He exists in a very different way to people understand love and morals to exist.
When you say then I understand why you need a rule book to live by. We are very different people, as what I want to do is usually moral too. Perhaps this is the problem - you assume that everyone else would naturally do wrong because that is what you 'want to do'. I don't run around raping and pillaging because I don't want to.
Your argument for morals having no meaning without God is biased. Most humans, of whatever religion, creed, ethnicity or intelligence know that wanton murder, rape, theft etc are wrong. We see exactly the same in the animal world - animals do not generally wantonly attack others of their species. Has God instilled morals in them too? If you say morals are doing what God says then they are not right and wrong - just pleasing, or not, to God.
It is funny that you give the example of the murder of a million people as being immoral given the mass murders and genocide that the Bible attributes to God. (I'll not list all the verses - it's rather dull, and I'm sure you'll know them.) Was God immoral or morally shcizophrenic?
