No, it's pretty simple. Without god. Not having god. That's all atheism is. You are apparently trying to turn it into a belief that there is no god.
For argument sake I will grant you “without god” now what? What does that prove? What is it? Is it without out god on Monday’s? Without god at work? Without god on vacations? Notice the incompleteness. It is a cowardly position to take.
A believer will say "I believe there is an invisible table in the middle of that room." A nonbeliever will simply say it's an empty room. They would not say "I absolutely do not believe there is a table in this room".
When it pertains to Atheism or Theism the issue is not the empty room but the existence of the invisible table.
