In life and after life we have two stages of existence
D = Dead/not alive
A = Alive
in between Dead & Alive/Alive & Dead we have
B = Birth
DE = Death
so if we go from D to B to A to DE to D or
Dead to Birth to Alive to Death to Dead
why cant we go from DE to D or Dead to Birth a second time?
and in fact if we have an eternity of nothing after death then we go an eternity in the realm of nothing? yet mathematicians have proved that within an eternity everything possible must happen? right, so then the possibility of going from D to B or Death to Birth must happen and we know its possible cause we have already gone from dead or not alive to birth once to prove its possibility. give it a few reads till you can comprehend it, but if you think about it there is no other possibility than another life I dont know how and when, that's all guess work but the possibility of going from not alive to birth must re-emerge from the supposedly nothingness after this life.
