Since professional exegesis on the bible, on its history and origins as opposed to its context has been done you can pinpoint its origins within a 100 years or so, so you can find the beginings of the One God concept and under what conditions they were written.
Man has always created Gods as to his own needs Odin,Kali,Jupiter,Allah,Yahweh e.t.c the list is endless.
Even early man thought modern day natural occurances vengence of Gods tsunami's, volcano's,thunder,lightning,pestilence e.t.c. and thought gifts/sacrifice would appease this. This was the only logical explanation at the time mysticism becomes triviality in the blink of an eye.
One God concept the ideals of a one God as opposed to a range of Gods,a God of Gods has not always been around.Through the crusades it wiped out many forms of deity worship deemed as heresy, for the 1 true God.
The literatary content, bearing in mind not many people could read or write and scribe was a much sort after job so story's which gave foundation to heritage were handed down by word of mouth.Think of the distortion between what your grandad told you a about life and how you see life today.
A few generations of chinese whisper's and =
Noah built an ark took, two of evey animal and sailed out in the flood which covered the earth.
There is a flood or poss tidal wave, the land cannot feed the people or cattle,a man named Mo-ah (poss) has a fishing boat and takes 2 of every animal they know 2sheep,goats,camels,dog,cows and thats prob it and sailed out to sea to find somewhere green,as man did not travel as a norm their knowledge of the world was around 500sq miles (in my opinion).
Jesus cured blind people, we know that in india and other parts of the world they were removing cataracts well before the time he was about,and as he travelled the chances are that someone showed him how to do it.
Fed the 5000 with a few fish and some bread, divide the 5000 by 3, double the amount of food, you make fish soup with croutons,you can ferment a variety of plants/fruits into alcohol some only take a few days you have water into wine.or they had some wine but watered it down.
Most things are hugely glorified but are probably an everyday norm now,which is not to say it didn't happen.
My belief,religion,tribal tendancies or eccentricities revolve around man and nature only so there is no needs for gods,god,paridise,hell.
I put some posts on 'Proof of god' posts 72,74,76,78,80 as to the difference between reality and existence because there is a big and defining difference between them both.also in 'the modern prophet'
I've got a book which i've been reading for about a year or so it's written by one of the greatest theologian's a Jesuit called 'HENRI DE LUBAC' the book is 'THE DRAMA OF ATHIEST HUMANISM' publisher 'IGNATIUS' which is his look at the great philosophers and fact, and gave me understand as to both sides of the argument. There are many things that exist which are not real type into google, if it exists you will find it fairys,unicorns etc you get sites for them because they exist but they are not real. If you type in Tabblefunkichocohol you should get nothing as it is not real and doesn't exist there is nothing wrong in hailing the existence of God as long as you can percieve the form it exists in,you cannot say it doesn't exist becuase it is not real or there is no proof as many things exit which aren't real but we don't question their existence. Pheew I need a cup of tea
