I think you're conclusion that any supernatural or guiding force must be sentient is making an assumption, first of all.

But more importantly, you give the Book of Revelations too much credit. When it was first written it was thought to apply to the here and now: God was coming back really soon. Of course, when this did not happen, people didn't say "Well, the BOR is BS", they said "God must have postponed his plans for a few millenia so he could go out with friends or something."

People have said that the end-days are here throughout time, and have applied the Book of Ambiguous Details to every concievable situation (Napoleon and Hitler were both Antichrists, for one) so what good is it? Why does God's divine message to humans sound so much like an LSD trip?
