Somebody as in “Somebody did something” is the more theological version of “Something came from nothing” for no reason that can be derived from current physics.
A logical, reasoning, thinking person would never look at a chair and wonder where did that chair come from? It didn’t just ‘appear’ out of nothing. Someone designed it, someone cut the trees, shaped the wooden pieces and then assembled the completed item. People would say you were crazy to believe that it ‘just appeared’ as it is.
Yet, those same people can look at the entire Universe and say that very thing that they would ridicule someone for saying about a chair..............
