Hi, I personally have no idea what you are going on about at the moment but I would like to put in my 2 cents on 'did the great flood happen?'.
Firstly, what makes us think that the great flood was worlwide? It was designed to wipe out all corrupt human life. As at that time there is evidence that ancient civilisations lived close together a global flood would not be absolutely necessary. However, as a theistic evolutionist I don't believe the 4,000 year stuff really although there maybe a point in seeing that there is nothing surviving from before a certain timescale. Who knows if it could hav happened 4,000 years ago although I personally think it was probably less recent nearer to the time where civilisaton was more or less centraly based.
