The farsight team and Courtney, stated we will get physical contact with aliens, i consider its kind double edge sword, first we would know who is on our side, but then all beats are off, i dont belive that good aliens can save the Earth and humanity neither , what i see that they dont want us influenced by the bad ETs and that we become a part of other star empire.
In regards to my past life , i can only say the battle will come, wether it make sense or not, but the battle for Earth will happen.

So . . .

Like example scenario 1: we all die from nuclear holocaust but the real war is do we (or many of us) move on to escape the planet?

Or scenario 2: we pull another heaven's gate, drink the punch, but we're ready to fly past the death traps

Or scenario 3: we join forces with some AI singularity of our own make, develop anti-gravity and a bunch of other tech, side with liberal ets, and physical reality is still a thing.

Any other scenarios I'm missing here?

Oh like slow seeping, just everyone naturally dieing but not reincarnating here. Interesting.
