I neither believe, nor disbelieve. I am the true agnostic - not only don't I know, but I recognise the impossiblity of my knowing, without the evidence.
What I do have are views, which you know, and I have patience, which again you know. Anything else is pointless.
Once that is accepted, all that is left is the gathering, and validation of, evidence. Since I don't get to take blood tests, I concentrate on the latter, specifically testing the theories.
None of them have come close to passing muster yet. From either side. And so I remain agnostic, and waiting.
