Life after death?

[Purplundy]

Welcome.

In my opinion, one seems more reasonable than the other, so we can't be sure there is just "oblivion" after death, but as there seems to be continuing evidence for brain being the sole "control center" for our consciousness (i.e. monism), then one can only reasonably conclude that when the brain dies, all of consciousness dies with it.

That makes perfect sense.
The afterlife is officially the fuzziest area of anyone's knowledge, but basically, my take on this is that the aggregate of the things that make us who we are as individuals, like our relationships, beliefs, and actions, constitute what you might call a 'soul', and that exists forever because no person's existence is undoable.
And yes, this immortality in no way involves soirées with winged angels in the clouds.
