is my idea of the afterlife possible at all

[Darwinian]

is there any scientific (physical,biological or chemistry) paradoxes or objections to my idea which is:

after a person dies

his consciousness/ sentience is brought back or recreated in a metaphysical/supernatural form by God (not restricting him to any religion) to reside in God's realm eternally.

now I know that in this universe we need a brain in order for consciousness to work.

So what if this metaphysical/ supernatural God can provide a metaphysical supernatural brain for the metaphysical/supernatural consciousness he recreates or brings back

sorry for using metaphysical/supernatural everywhere

if this is not possible AT ALL please explain why

I suppose that it may be possible for a super advanced alien race to come back in time or hop across parallel universes to the point just prior to brain death and then scan your brain in incredibly high resolution (without anyone noticing) and then recreate that pattern/structure either in some form of virtual reality or in real space and thus 'you' continue to live on after the death of your body.

But would that be you or a copy of you and it's also quite possible that I've been reading too much sci-fi :S

Anyway, even if that were possible it would have nothing to do with this character from the Bible you call God.
