No it is not if that was true then Jehovah’ Witnesses and all sects of Christianity would not be bothering people who are Jewish and trying to convert them away from the G-d of Abraham Isaac and (J) yacob…Coming to the doors of their homes accosting them in the streets and bothering them while they are sitting down for a meal or leaving literature on their cars… Your argument is false…You worship another… There were many gods that others worshipped before each one had their own “ bible” which just means written document…Your sects are just better at covering up and deceiving the naive and uninformed…I have seen what the southern baptists do with there fake houses of worship and dressing up like Rabbi ‘s there is nothing they would not do to push their agenda…Jehovah, though not original Hebrew refers to Yahweh or יְהוָ֔ה. It is simply a matter of language but refers to the same being. Your argument is that because the language included a "J" that the person never existed. Most people who read these translations understand that Jehovah is Yahweh or יְהוָ֔ה. You seem to believe that he never existed because he is referred to by and different name. No matter the name, they are all referring to the same being. If it makes you feel better, substitute it with Yahweh since it is the same being I am referring to. To me your argument is ridiculous. Just because others in history have referred to a particular being in history with a somewhat varying name does not mean that the person they are referring to did not exist.
