I think most religions' end-of-the-world stories are pretty crazy, although the multiplicity of takes on the Christian one means it's really confusing to take them all together, and their cultural dominance in the US means that people try anyway. :) Does the Resurrection of the Dead happen before believers are called to Heaven? Depends which denomination you ask! I used to have a great apocalypse calendar diagram back when I was studying apocalypses but now I can't find it.
