The Septuagint was created long after the NT was written...
This statement is historically inaccurate.
The translation was made from the Hebrew Bible by Hellenistic Jews during the period 275 - 100 BC at Alexandria. Initially the Septuagint was widely used by Greek - speaking Jews, but its adoption by the Christians, who used it in preference to the Hebrew original, aroused hostility among the Jews, who ceased to use it after about 70 AD. It is still used by the Greek Orthodox church.

Historical evidence that the Septuagint was know the Greek speaking Jews before the birth, death, resurrection and ascension of Jesus. And it was known to Greek Speaking Jews before the Council of Javneh in AD 90 decided the Canon for the Hebrew Canon. It is also known to the Ethiopian Jews who accept it as canon today. The Catholic Church did not add to the Bible; in fact the Septuagint was Sacred among the Greek Speaking Jews and the Ethiopian Jews.
The books within it are known in other Ancient text and writings as mentioned in the video. All Seven of the deuterocanonical books rejected when the Hebrew Bible was decided are found in the Dead Sea Scrolls. Some scholars thought the LXX was unique to the Alexandrian Greek-Jewish people, but fragments of all of them have been found in Hebrew and or Aramaic among the Dead Sea Scrolls. This means they had a wide and multi-lingual circulation among the Jewish people.
There are people who claim that the Council of Javneh never happened. But, these Jewish Encyclopedia's say differently. BR> (The Encyclopedia of Judaism, vol 15 page 117)" says that the limit of the third part (Writings) was not finalized until mid of second century. In addition, the Hebrew Canon was also not accepted by Ethiopian Jews who accept Septuagint to this day "
(Encyclopedia Judaica, vol. 6, p. 1146)"There is no evidence that the Rabbis at the council of Javneh (90A.D.), had the legitimate authority to determine scripture for the Jewish religion"
(Encyclopedia Judaica, vol. 6, p. 1147)."The group of Jews which met at Javneh became the dominant group for later Jewish history, and today most Jews accept the canon of Javneh. However, some Jews, such as those from Ethiopia, follow a different canon which is identical to the Catholic Old Testament and includes the seven Deuterocanonical books."
(Encyclopedia Judaica, vol. 6, p. 1148)."Protestantism derives its Old Testament Canon from the European Jews who followed the Canon of the council of Jamnia or Javneh (90 CE.)."
Honestly, I think you insist on being contrarian sometimes. What possible motive do you have for denying the early composition of the Septuagint?
It was already an old story to Philo, who died sometime between 40 and 50 A.D. when Christianity was barely a blip in the Empire:

So it’s complete balderdash that it was “created long after the NT was written”.
