Hmm, Coco, let me try to answer these from my perspective.
The main point, though, is this: most atheists might not believe that faith in a god is generally a good thing. But even if they did, the point is that from oyr POV it's basically an irrelevant question. To an atheist, saying "believing in god is good" is like saying "a cure for AIDS is good", i.e. Even if we were to agree the point still stands that the supposedly good thing doesn't exist. So you're really looking at this in a way that doesn't make much sense to us. Nonetheless, let me try and address your points:
1, 5-8 I would summarize as a belief in god basically being comforting. This doesn't apply to atheists, as we, understandably I suppose, take zero comfort from something we consider to be false. Of course we still find reassurance and comfort in many of the same things religious people do as well, family, community, ranting to strangers on the internet, etc.
2 Is a really tricky one. Enter the problem of evil. What is the reason god is letting Somali children starve, then? And how is this moral, since God could presumably stop it? Whole essays have been written on this, suffice to say it comes with a whole rat tails of issues attached to it.
3 If you can prove this in a double blind study the setup of which convinces a panel of leading research scientists from a variety of disciplines, I am willing to convert to your religion and give the rest of its claims the benefit of the doubt. Hasn't happened yet, though. Wonder why?
4 Like what? The origins of the universe or something? If any religion can prove this, again I'll convert in the spot and this time there won't be anythng left to doubt.
9 & 10: Fine, I personally happen to think that one of the primary reasons why people believe in gods is this. Or more precisely, the fact that they are afraid of death. That doesn't make it true. And the good news is that probably we won't have awareness to be upset that we're dead and miss our loved ones.
