Are they all tested for authencty?
yes they are
Can we still investigate them?
yes we can
Are they all 5000 the same?
No they are not, but with 5000 copies it's much easyier to find wich have alterations or spelling errors, then with 3. Making the bible one of the most authentic books in history, since no book prior to the renaissance has as much copies.
Then wich one is the right one?
The Textus Receptus is the one and only bible used today for all it's translations (excluding the KJV wich is a translation of the latin vulgata), it's the bible tested for utmost authencity based and compiled upon the 5000 documents, and confirmed in authencity by death sea scrolls and others.
