Per my understanding;I am an Agnostic, not an Atheist, but I can answer your question anyway. Is your question asking if an Atheist would believe you personally or believe that logistical glitches such as your example really do happen? The correct answer is YES. Furthermore, your question makes a fundamental miscalculation. You define what God is first then you will deserve an answer.
Atheist = "Belief there is no 'God'. " (Definition of "God" TBD)
Agnostic = "Impossible to know if "God*" Exists." OR "Not convinced that "God*" exists.
* = need a workable definition of how you define concept of "God".
