Hello Feebs.

These are all good, fair questions, and I'll try to give a reasonable answer to them.

1.)What makes today gods different to any of the roman gods who we know are not real?
It depends on what you mean by "not real." Were the Romans right to believe in Divinity and that they rely on Divine Power as does the entire universe? No, I don't think they were. Were they wrong to believe that such a higher power was owed worship, and that injustice was hated by said High Power? No, this is correct.

Really, what the Chrisitan critique is, is not saying "you're ALL wrong, oh heathens", but "you're saying incorrect things about God - you're projecting the worst parts of your culture upon God." Thus, they erred in dividing up the powers of God into seperate cults and deities. They erred in ascribing human motives and failings to the Divine Power, etc.

2.) What happens to god when all the humans on earth die?
Putting aside for a moment the idea that God will always have mankind with Him...really, nothing would happen. When Moses asked God "what is your Name?" the Lord replied "I Am That I Am." In other words, He simply "is" - our existance adds nothing to Him, nor does anything we do diminish Him. This is why the ultimate "why" of our existance will always remain a mystery - who can understand the most hidden reasons of the One Who is infinite?

3.) Why did the one god choose Earth as his planet were he would start a civilization which would end up destroying itself in the end. (Im not saying we will destroy ourselves, but i think its pretty inevitable.)
I don't know that it's correct to say "earth is His planet." It's all His. While I don't have any snappy answers to say how extra terrestrials would fit into a Christian cosmology (though I have given it some thought), there is nothing to say that they do not fit into some common larger scheme with us.

4.) Why is it then that God can be here forever and not have been created if it is impossible for something to be here without being created.
Good question. If you want to get down to the nitty gritty, the answer requires one to take a view of things they may not ordinarily have.

We often look at things in terms of "past, present, and future." While that is certainly how we experience this univese, indeed it seems to be our hard wiring...it's not the only way to perceive things. It's not the only possible way. Just as our linear experience of time often takes the form of a "line", the totality of creation (visible and invisible) could just as well be pictured as a "bubble". A bubble or sphere, floating within a greater sphere, which not only exists beyond the lesser sphere, but infuses and permeats it. And what is beyond that? Ultimately, God.

But what all of these created, "lesser than God" realities have in common is that they are limited. They are "circumscribed" - they have a begining and end, whether you look at it in a linear way (where applicable - really, only in the material realm), "spatially" or even "conceptually."

God on the other hand, is beyond this. Thus, I know this universe is not God (which is really what you're asking), because it is clearly perceivable, multiplied, and limited.
