Without open minds the earth would still be flat.
And without repeating some of our experiences, we believe that something is going on in the background.
Todays knowns were yesterdays unknowns, and do yoi really think there's nothing more to discover??
I think of death and whats after as certainty that there is nowt else. So in this regard yep,I dont think there is more to discover.
At the end of the day we are just animals which happen to be at the top of the food chain.
Do people who believe in something else also believe the same is happening in the rest of the animal kingdom ?
Maybe the lost souls of ghostly bunnies running across the moors, or the spectre of a dead spider in the corner of your living room. Like all living things, we are here to procreate and pass on our genes to the next generation.
