Furthermore, every atheist I encounter actually asserts something like "I do not believe in God, because there is no God." After all "I do not believe in God, because there is a God" is irrational and, given the consequences of disbelief if God is as described in western tradition, exceedingly foolish. Atheism is only a rational belief if God is known to not exist. Otherwise it's no different than not believing in climate change or dinosaurs.
And in any event a transcendent creator God (first cause, etc) isn't anything at all like the easter bunny, comic book superheroes, or bad fictional characters.
