Perhaps our nature does not allow us to grasp this knowledge. We have the gnawing, intuitive feeling of there being something after death, something
above this world, but we cannot put our finger onto it, and the vast possibilities cause us not to narrow it down to anything specific.
What religion does is put our mind at ease, and gives us an excuse to not question our existence and any other realities which may be overlaid into
ours. This is why there are so many people who choose to believe a religion. If only Christianity were right, why are there so many other religions?
And if they are right why are there so many others? Although at the heart of every religion there is an afterlife, and there is an authority figure -
a God or Gods.
It displays our vulnerability to the true harsh nature of the world, and those who choose to believe in one religion and bash others, I'd like to
redirect you to
this recent thread.
We need an authority figure to judge our lives and tell us where to go, and what to do. This shows our weakness in the face of existence.
How I'd like to reply to the OP? Perhaps this is all true - but what if we enter this physical world to experience a physical body and to gain
enlightenment concerning the feeling of possessing inside an imminent and inescapable death. The search for a meaning. Physical pain. Helplessness
before a vast and infinite universe, which is just an image. When you play a game, there are boundaries you cannot cross. This is precisely what the
universe(s) is (or are - if believing in the multiverse theory).
When outside of a physical body, the details of which I will not go into, this vastness is nothing to you, there is another vastness you begin to
face, which is the infinity of consciousness and knowledge. We all have a craving for knowledge, and this physical life is just another little piece
of enlightenment.
There are restrictions, of course. We are not allowed to know of our infiniteness, because this would cause us to not value this life, to not learn
anything from it, and to not feel this empty, lost feeling. We would commit suicide, and relieve our suffering. In a way, this information would kill
you. Ignorance is bliss.
