Ok, please read before answering. I 99 percent believe that there is nothing after death (and I'll explain why with some points me and a friend were talking about). 1 percent believes in reincarnation. I still have huge hope for the afterlife but I just doubt it so much
The reason is because of diseases that affect the brain. Mainly Alzheimer's and dementia. Now, I saw my grandmother suffer from dementia and of course, as the neurons died, she got progesivally worse and worse until she died last year. As painful as it was to watch, it made me believe in nothing after death. After total death, we all know that all neurons in the brain are dead, and we know from brain diseases, that when neurons die, our memories get "deleted". I've taken a drug once and forgot who I was. Ee witness it in patients. So since the afterlife requires memory to experience it, what makes people think that once the brain is dead, we live again? I hope this makes sense.
But my buddy brought up an amazing point. Since the universe is proven that nothing "existed" before it and nothing brought everything into existence, what is the probability that something comes from nothing after we die? That something being the afterlife. However, the probability of the universe existed was astronomically low. The chances of something coming from nothing have more than 1 to 100 trillion chance. So when we die, it could take reality billions of years, until you can experience the afterlife.
What do you guys think?
