Agnostics?

Have been reading a bit more about "agnostic Buddhism"' and as always there's much on the Internet about it. A useful thought provoking set of exchanges are shown here. I will be looking into this more over the coming months, but for now I'm happy to simply learn rather than express an uneducated view. My standpoint will be from a scientific rather than faith based perspective and I find the idea of rebirth quite challenging. But I have a lot to learn, and will do so with an open enquiring mind.
