As for Satan being cast down to earth, that's why I didn't say that I know that the heavens never had problems like that of earth. However there is no reason to believe wars in heaven occured where spirit creatures are killed like they are on earth. A war in heaven is not going to be a very tangible thought and requires a war on earth to even logically contemplate the idea.
Sab - This still does not diminish the point about war in heaven. The bible never specified anything about the control of earthly kingdoms transferring over to the good side. The idea that God is backing the U.S. or still backing Isreal has no support in scripture.
Futhermore, If god is working on making heaven on earth in gradual fashion, then his attemps so far have been very unimpressive. Sab a person of reason could hardly accept your explanation of what god is doing now because it's all speculation.
So let's summarize.
1. We see no evidence of god acting in our time.
2. The scriptures don't support this position.
3. Freedom and science have gotten us to where we are today.
I think the choice is quite obvious. Keep religion in your living room!
