Ok, the idea of an afterlife appears to be widely rejected in this corner of answers, I would like to bring a new point to the table. Ok, in Einsteins string theory, he suggests that there are higher dimensions than our 3D space plus time, totaling in 4 dimensions we can comprehend. Now, humans physically exist in 3D, but our minds can comprehend a 4th dimension when we cannot feel, but we are aware of. If we can be aware of a dimension we cannot see that suggests that our minds (not brains) can operate in higher dimensions. Thus, after death it would be possible that our conscious minds could still exist in higher dimensions, but our physical body’s would not. So, my question. What are your thoughts on this?
Einstein set the foundation for the string theory, http://www.hyperhistory.com/online_n2/History_n2/index_n2/einstein_theory.html
Also, though the human brain only exists in our braneworld, consciousness cannot be proven exclusive to our 3D world, considering we cannot comprehend higher dimensions or know what the hold.
And yes, I know that the fourth dimension is time.
Additionally, you cannot come to a set conclusion as to exactly how the brain and mind operate and which governs the other because if you knew, then you would know more than what modern neuroscience is capable of explaining.
I might add that the mind is not necessarally part of the brain, it is quite possible that the brain is influenced by the mind, which is not a physical material. http://www.cerebromente.org.br/n04/editori4_i.htm
To the question, why didn’t your afterlife occur before birth. Simple, it quite possibly could have be occuring, but at that point it would be a “before life”. Can you remember back when you were in the womb?
