My basic point is that Christians have no more "on the table" than followers of Islam or Judaism.
All have ancient texts that teach them certain things. But there is no corroboration of the religious ideas set out in any of them. Sure, there is some history in the Old and New Testaments, but you'd expect that since they are largely written in the style of a historical narrative. The mention of some historical events is not evidence for the accuracy of the religious content.
So there is no reason, on the face of it, to give the scriptures of Christianity more credence than those of Judaism or Islam. (Certainly not just because the bible says it is true, so it must be! If you buy that sort of logic, then I have a used car to sell you
)
The reason one may be inclined to accept one rather than another comes down to aesthetics and tradition, it seems to me. I was brought up a Christian, so I know fairly well all the wonderful stories about the life and teaching of Christ, and the imagery, the art and the music (especially the music) it has inspired in Christendom over 2000 years. These things help to guide and inspire me in life and are welcome constants amidst all the changes in my circumstances. But I am 100% sure that the same is true for Muslims and Jews, in the form indicated by their own religious traditions.
