Feif un,
the world being old dosnt contradict the torah so why do you have to come onto a theory that has has absoloutly no proof backing it up, the fact that hashem could have made the world less then six thousand years ago is not a proof that he did, and untill there is such proof why should we assume that this is what happend when evreything physical points towards the fact that it didnt? just because gedolim of a previos generation beleived somthing SCIENTIFIC (as opposed to somthing in religion or anything else) to be true (that the world is young and that the sun circles the earth ect.) dosnt make it necesserily true as there knowledge in science was taken from what scientists at that time beleived.
