Is there any specific revelation in the bible that really authenticates the bible?

Science fiction has made movies of many things that have come to pass, laser lights, teleportation, which many Yogis are capable of, many many things. We are all connected, and many of the inventions imagined have come from ideas people sent out as thought forms in the ether. None of that would be proof to me. The Bible is self contained, you must believe it because it says so, and has everything covered, if you question things, there is even a verse that says you don't need to know anything more. I believe there is much proof in the Bible if the stories are true of ET intervention, a new book about it is "Is Jehovah an ET?".
