If there's no life after death, then your existence ends forever. But your non-existence lasts forever, because no one can give existence back to you, so in a way you become infinite. Does that even make sense? Fuuuuck, I'm gonna go burn some more Sour D.
There has to be something after death. We are energy. Energy cannot be destroyed, only transformed. Just because our physical bodies die off does not mean our energy does.
if there is something, we wont be cognate. at least thats what I believe. i think your conscience is directly linked to your physical being, and whn you die, bye bye conscience. the energy, may be reused in the dirt/whatever my atoms bond to, but we wont be attached to a tree saying WOW!!! im a PLUM!! i didnt ask the sun to spit out my atoms...
