I believe that there are only 3 possible options. 1) That God or some all powerful being created the universe. This is a very bizarre state because it means we are all subordinates to an independent being that has always existed. Strange. 2) The universe was created out of nothing. Truly weird. 3) That the universe has always existed. This is simply incomprehensible.
Because these are the only 3 options I see and because each is mind-bogglingly discouraging or incomprehensible - or downright goofy - I think this whole existence thing is either some sort of hallucination or a complete joke. (Another possibility is that I am in some sort of hell.) Therefore, I take nothing seriously and treat this whole thing sort of the way you deal with the pain of stubbing your toe. Kind of grit your teeth and wait for the pain to end.
