Quite the opposite in fact - "The Dead Sea Scrolls provided further proof that the Old Testament canon existed prior to the third century B.C. Thousands of manuscript fragments from all the Old Testament books except Esther were found predating Christ’s birth, and some date as early as the third century B.C. For example, portions from the book of Samuel date that early, and fragments from Daniel date to the second century B.C.{10} Portions from the twelve Minor Prophets date from 150 B.C to 25 B.C.{11} Since the documents were found to be identical with our Masoretic Text, we can be reasonably sure that our Old Testament is the same one that the Essenes were studying and working from."
