Proof there is an afterlife!

Right I away I will admit that I am a Christian that believes what the Bible says. Hence I believe in a Heaven and Hell.  But I am here not to prove the existence of Heaven or Hell, but I'm going to attempt to explain my theory on why I know there is Life after death.  Right up front I will say I believe in ghosts and am fascinated by the ghost hunting shows and believe they capture actual footage of people that still exist after passing away, but this not my attempt at proving life after death I'm just stating it as evidence.  Anyway my theory goes as follows...   I have no way of proving to you that I am conscious and aware of my existence besides the fact that I'm telling you now that I am conscious and aware.  But lets say when I am 35 years old I get hit in my head so hard that all memory even my name gets wiped out of my head.  I mean I don't remember a thing and my memory never comes back to me.  For all I know waking up in that hospital bed is my first day alive.  But it wasn't! It would seem like my first day alive because I don't remember my past, but as far as I would know, I would think I was born a 35 year old man.  What does this have to do with the afterlife?  Well lets say when we die we turn into nothing, being non exsistant, no consciousness no memory of our life just nothing.  Well just like me thinking I was born a 35 year old man, and my first day of consciousness being when I wake up, If we were to have our memory and consciousness wiped clean when we die, we would already be there as far as we know.  If we are not going to be able to remember a thing after we die, we would already be unconcious of our life and pretty much not know we ever existed. I hope your following me because many people loose me there.  I mean, if we are going to return to being nothing, we would already be unaware of our lives!  Since we are conscious of ourselves right now, and know we exist, that means in the future we will be able to look back at this moment and say yes I remember reading that article!  And since we can't return into being nothing (actually maybe some people might, I can only speak on my own behalf of being consciously aware) that means after we die, in one way or another you will still be able to say, yes I remember when I was alive and read that article, (actually the Bible says our memory will be even better after we die).  Do you follow me? I hope so! It's so hard to explain but if you think about it, it makes perfect sense.  If it makes sense to you then this next part will be cool to you.  I can't tell the future, but I kind of can!  I know one thing about my future that can't possibly happen... I know I will never be hit in my head so hard that my memory gets wiped clean!  Since I am conscious right now, and can remember yesterday, and my past, I will always be able to remember!  Because if my memory gets wiped clean, I would think I was born on my first day of being awake and aware.  Now I know this is complicating and I would love to hear what people think.  Please comment or ask questions or give your ideas.  Let me know if what I said did or did not make sense.  Thanks!
