There were a number of people who are reported to have seen him alive, then dead, then alive. You, it seems, reject their testimony but yet accept the testimony of those who say George Washington existed. I am not being critical of you. We all have to set our thresholds for proof. I accept it based on the testimony of creation.
Faith is faith.
The issue is the quantity or quality of proof that you require. I accept it based on the testimony of others. Again, here, there is no reason to rely on faith - never mind the fact that the claim is relatively inconsequential. Or have you merely accepted it. If you say yes then I maintain that your threshold for faith is just higher than mune but it is still faith.
