Atheists and Abrahamic theists, will solitary confinement prove the ultimate truth and reality of atheism to..?

well i tend to be afraid of being alone... without human interaction... so after long enough i would either do one of two things... withdraw into a made up reality inside my own mind and watch as that plays out.... or begin contemplating all the mysteries of life... and start writing a book of philosophy on the walls... as long as i only wrote a bit each day i wouldn't die of blood loss...
