I'll bite.
First, why would you like to wonder if the atheist can do these things? You are wondering. Your passive voice is very annoying. This also might be why you have to look up at what you wrote to follow what you were saying.
Here's your problem. What's the difference between god acting gravity out and gravity acting itself out with out any god existing? Or that you have actually spoken to god and not imagined it?
In other words, how can you qualify god?
The atheist's evidence for no god is the lack of evidence for god. Would you think the mastadon existed if there was no evidence for it? Would you even think that a mastadon might exist, even if there was no indication it ever did?
Until the theist can show concrete evidence for god (they haven't yet, especially if you listen to rob's claptrap), the logical position is that god doesn't exist.
As crash says: abscence of evidence is evidence of abscence.
