I am saying that if a thing isn't credible like the creation stories, the flood and those surrounding the life of Jesus,then for those who claim they are true they have to put up the evidence, but of course they can't.
Well for a start, you obviously aren't aware of the fact that the Bible needs to be read as a collection of materials comprising differing literary genres; mythologies, histories, testimonies, lists, hymns, poems, proverbs, wisdom literature, eschatalogical speculation ... to lump everything into one basket is, in the face of modern scholarship, nonsense.
To assume that just because one can read, a 21st century, English-speaking reader will understand a text written with a Semitic or Hellenic sensibility is, equally, a nonsense.
You cite three examples, to which I shall respond:
The creation stories
The 'creation myths' are a metaphysical discourse in the mythopoeic style of Semitic literature. The material elements of the discourse — paradise, the Garden, the four rivers, the two trees, the serpent, the primordial couple, is a rich metaphysical discourse which sums up the idea of God, of man, and the relationship between the two, according to a contemplative appreciation of 'the human condition'. To say the discourse 'lacks credibility' makes the fundamental error in assuming the discourse should be read as 'history' in the modern and common sense. That shows a degree of ignorance regarding the way to read the Bible.
So while the material
The flood.
There is indisputable geological evidence of significant catastrophic floods in the region. To say there is no evidence is simply to ignore the facts.
The stories surrounding the life of Jesus
This is one of my favourites. Until quite recently, critics assumed that Luke was 'making it up' because he spoke of places that didn't exist, he referred to known historical personages by titles that didn't exist, he justmade up stories to suit his narrative ...
... then archaeologists found the places 'that didn't exist', and they found evidence of personages known by titles 'that didn't exist' ... historians of Rome use Luke's gospel as a reliable 1st hand, eye-witness, 'man in the street' account of life in occupied Jerusalem, because so much of what he says has been corroborated from other sources.
You fall into the Bultmann error:
A is a myth;
B reads like A;
therefore B is a myth.
It's flawed logic, although if you've a reputation like Bultmann's, you'll get away without being challenged for quite a while.
You are of course welcome to your opinion, that I do not dispute, but that anyone else should give it any credence, on the evidence you've offered so far, I suggest would be unwise.
