Is the Bible complete?

Ok, we know that there are difference between the King James version and the Roman Catholic version of the Bible. The king James version leaves out several book. But, I had heard long ago that the Bible is not actually complete. That the vatican is actually storing original documents that they do not want to have disclosed for whatever reason. Has anyone considered what they could be or even if they really exist or are a rumor? Also, what would happen to the world if they found out that the Bible actually talked about aliens or it was just a bunch of stories. I am not being sacreligous, just curious. Would your belief in God change?

Have searched only for a small bit and cannot find anything on the secret books kept by the Vatican, but I have heard that there are ones... Anyone have info on this?

No, the bible is not completed, and will never be.
