You are wrong.
There are many recorded death bed statements where family members have offered "religious solace" that was angrily refused by bitter old dying atheists, totally pissed off that someone would waste their last few moments with such nonsense.
There are also many who are perfectly at peace with their perceived status as "Happy Accident", who truly agree with the old quote:
"I do not fear death, in view of the fact that I had been dead for billions and billions of years before I was born, and had not suffered the slightest inconvenience from it."
I know it's really hard for you to imagine anything outside of your own personal experience, and that you think you "know" things that can't be known, but I assure you, trust me, you are wrong to believe that there are NO "true atheists".
