"who created it" implies a causal chain of events whereby someone is responsible for the bug. This is Safety-I thinking. John Allspaw addresses this when he states that "there is no root cause" for an incident or bug. So in a very practical sense YES the bug is "born" at the moment the user "discovers" it. Note that "discovery" here is in the imperial sense where the the user has drawn a line on the software map (so to speak) an labeled it: beyond this here be bugs. Devops very directly implies skepticism for causality as a primary/default phenomenology for understanding bugs.
