Just listened to a program that presented explanatory postulation of cosmic evolution, and there are certain understandings of progression back to about three and a half billion years ago, and beyond that current scientific framework starts to loose it.
Funny how jws believe the culmination of everything is focused on "them in their lifetime" - quite a study in evolution in itself.
For the jws - that's 3700000000 years of projection of framed understanding, not inclusive of the so far unframed - the end is just around the corner, any moment now.
