Tl;DR > Why does anything exist? > Because necessity requires logical laws; logical laws imply incontrovertible truth; such truth includes mathematical truth; mathematical truth defines numbers; numbers possess number relations; number relations imply equations; equations define computable relations; computable relations define all computations; all computations include algorithmically generated observers; and these observers experience apparent physical realities. I'm not convinced. Does anyone follow this?
