Your logic is sound, however the argument that there is no evidence God exists is not correct. There is plenty of eye witness testimony. It is proper for you to say the evidence is not sufficient for you. Different people have different needs for evidence. That is why we have juries.
You are correct, however unfortunately, accounts are often looked at with skepticism when it relates to the supernatural, even though we’re more than ready to believe Hannibal crossed the Alps with elephants on accounts alone.
You are absolutely right. It is proper to say that there is not sufficient evidence. I don’t think that any number of eyewitness accounts alone particularly in an ancient text is evidence of anything. I also agree with you that different people have different ideas about what constitutes evidence. If someone is an eyewitness then it is rational for them and them alone to believe but it is also rational for someone who hasn’t had that first hand experience not to believe.
