I am not an atheist, but you are making to strong a demand for the criteria of non-belief to be an atheist. I can easily turn the tables that theists make evidentiary assumptions and the stance adopted that God exists, and an evidentiary burden being assumed, As long as this burden is not satisfied just how can anyone deem their position to be rational?
.Based on your line of reasoning the only viable choice is agnosticism.
And yet it is because of multiple independent pieces of concrete evidence that billions upon billions of neurotypical men and women all across the world have come to the natural conclusion that Almighty God exists.
