Though Maurice Bucaille is qualified in medicine not science, believes the bible is a load of trash anyway (paraphrasing here) and doesn't believe in a < 6000 year old earth.
"As for the Biblical genealogies which form the basis of the Jewish calendar and assert that today the world is 5738 years old, these are hardly admissible either. Our solar system may well be four and a quarter billion years old, and the appearance of human beings on earth, as we know him today, may be estimated in tens of thousands of years, if not more. It is absolutely essential, therefore, to note that the Qur’an does not contain any such indications as to the age of the world, and that these are specific to the Biblical text."
Its hard to be a scientific minded person and not come to this conclusion.
