No, this isn't a prediction of the battle over Heaven and Earth being like a scene from Star Wars, it is an intellectual exercise/exercise in creative writing.

What if there was an error in the calculation?
The end of the world, the battle between light and darkness, yadda-yadda, is actually to occur on 12/21/2112...or 2222, it doesn't really matter...

My question is,if we become a spacefaring species, terraforming and colonising other planets...what happens when Hell occurs on Earth?

Would space exploration be the ultimate biblical loophole? If not, how dcould other species of sentient, intelligent life from other planets play into biblical philosophy?

I don't believe in Prophecy, though I entertain the idea.

This thought exercise only redoubles my belief that we should, as a species, put all of our power of mind into advancing our technology and getting off this rock because...well...Armageddon can't happen across all of the universe at once, affecting all life...can it?

I dont know.. Can the apocolypse occur thruout? I wouldnt dismiss the idea, as our solar system is the size of some suns, so.. Technically, I suppose the apocolypse could transcend other parts of the universe.. For all we know, the entire universe is a single egg waiting to hatch, and when it does, BOOM! Apocolypse across the entire universe. To some extent I take that seriously.. I think the universe is trying to figure out what it is, and eventually one personality will ascend and become the one entity, but in a larger realm... Im confusing.. Im out

There are so many aspects of human life that relate to being on this planet in this solar system which appear connected to our physiology that it may be that we were designed to be here - and here alone. For instance, there is a connection between the sun's magnetism and female ovulation. Perhaps women won't ovulate on other planets or in deep space, resulting in no pregnancies. Maybe that "connection" should be ruled out first.

The hell is not / will not be ON EARTH.

The hell, as well as paradise are outside the universe, outside our space-time continuum. When the "end" comes, it is not the earth that will be destroyed - it's the whole universe. Thus, those colonies of yours won't be of much help ...

I don't believe in prophecy either. I think events can always change as people change.
