this show had nothing to do with god
or any kind of spiritual crap
thsi was plain and simply what can happen
most likely its not but it could

for example
they were talking about
yellowstone national park
under yellowstone lies one of the
worlds most volcanic places
if that place blows up
its considered a supervolcano
the ash and debris from that explosion
would block out the sun which will trigger
other things to happen

in 2029 some asteroid is predicted to reach our atmosphere
and dip below communication waves
6-7 years later its on course to return even closer
