@neoyokio sent me this really interesting article a while back:
https://www.newscientist.com/articl...ow-your-brain-conjures-up-your-sense-of-self/
The way I see it is- we're only able to contemplate the fact that we are alive because we have a highly developed sense of self awareness- consciousness. I think- partly because we don't understand it and partly because as a race- we have such enormous egos- we tend to think that part of us is magical- even immortal.
At the end of the day- it's personal belief because there isn't definitive proof either way. I myself do also have a spiritual bent- so- I do understand the appeal.
Still- after reading that article- it could well be that this sense of self/consciousness has merely developed as a by product to the way the brain works! Either way- I don't really see it as being separate from the brain. I'm not convinced it can exist without a living brain- either before birth or after death.
I suppose it depends on what you mean by 'Did we exist before we were born?' Exactly what part of us are you talking about? Biologically- yes- the female egg we came from was created when our mothers were. The father's sperm probably got created a little later.
I'm guessing you mean spirit though- spark/consciousness/sense of self. Does that exist beyond- before and after our mortal lives? I think we tend to have this idea of a fully formed person's character when we think like this. But babies aren't born like that surely. They're surely living mostly on instinct at that age. We don't even remember the first couple of years of life!
I think it's said that children start showing signs of self awareness aged 15 to 18 months. Doesn't that suggest that it is something that develops as the brain develops? We almost learn it perhaps? If we were born with it- surely, we'd have memories from earlier on in life?
I often hear the argument from reincarnation fans about energy- that it can't be destroyed- only transfered. But our 'energy' IS transfered when we are born and when we die. The biological bits of us- egg and sperm were created from our parents- because they ate food = energy. When we die- we rot and feed the insects or- fuel the flames in cremation. I guess thoughts/awareness/consciousness are energy- electrical impulses in the brain or whatever but again- surely the brain needs energy (food) to function? It then transfers that consumed energy- calories into thought. Without food- it will die along with the rest of us. I can't see how thoughts survive beyond the brain and surely- thought is all we're talking about when we talk about 'us'.
