I don't know. The picture just grabbed me though and I just wanted others' thoughts.

@Acharyasman55 Looking at it in the light of day your question is more straightforward. I thought the picture was supposed to be a depiction of atheist thought somehow, and didn't recognize any of my thinking in there. You were ASKING for the thoughts of atheists.

In that case I think ... it's someone's fever dream about the meaning of life.

I'm not sure about the symbolic representation of death as another [re]birth. I'd have depicted it more like a brick wall. Then again simply that I was born 61 years ago is not evidence I came from some other realm or existence, so maybe the metaphor holds.

In fairness, I'm a pretty concrete thinker, innuendo and metaphor are sometimes lost on me. I'll pass this particular baton to an art major
