Was the name JEHOVAH used by the inspired writers of the Christian Greek scriptures?

Are you delluded or what, the bible is man-made book written by humans. Has so many mistakes and contradictions. If I was to state them all we would be here for years. Over 7890 different versions ( check wiki) with deviant sects. I just cant believe a word that comes from the book. Uncle JOE has a jehova version bible, Nan has a english version bible and then next your whole entire family will have a different book to you.. Now similariaties, in beliefs besides the 10 commandements which obvious is just basic human morals. I cannot believe that a normal rational person will genuinly believe that the bible is the truth. It cannot be truth, because it is man-made. And anything from a man I cannot trust.
