What must be considered here is that existence is a rather odd condition when you think about it. There is no real [i]purpose[/i] do existence, nor does it allow for acausal occurrences which, on a fundamental level, [i]must[/i] be possible in at least one sense of the term lest we neglect the fact that the state of existence is a rather fragile one. All in all, while this is physically sound, it creates a myriad of philosophical problems which make it quite objectively unlikely.
