What Mystery Bothers You the Most?
No mystery bothers me.
All mysteries intrigue me, interest me, invite me to investigate them.
For me, there is no mystery in those questions you pose.
For me, the evidence is overwhelming, that there is no meaning or purpose in life, other than the ones we adopt from culture or choose for ourselves.
What possible evidence could you have that there is any sort of “plan”?
Everything I see indicates that there is simply lots of different competing and cooperating strategies happening at many different levels. No indication of any grand plan at all.
Some amazing complexity in the strategies, in the levels of recursion, and feedback and interaction.
