Rubbish again. The Torah is much more recent than that.
The Torah is the result of a long process of editing (or redaction, as it is called by scholars). This means that there is no one date that one can be pointed to as the date of composition. Most scholars think that the final major redactions took place after 539 BCE, when Cyrus the Great conquered the Neo-Babylonian Empire.

Also, people of "most nations" (that is, people living in the Roman and Persian Empires) became acquainted with it only many centuries later.
Here is the Torah being introduced to the Jews. This event was subsequent to the return from the Babylonian Exile.
Nehemiah 8:5 Ezra opened the book. All the people could see him because he was standing above them; and as he opened it, the people all stood up.6 Ezra praised the Lord, the great God; and all the people lifted their hands and responded, “Amen! Amen!” Then they bowed down and worshiped the Lord with their faces to the ground.
7 The Levites—Jeshua, Bani, Sherebiah, Jamin, Akkub, Shabbethai, Hodiah, Maaseiah, Kelita, Azariah, Jozabad, Hanan and Pelaiah—instructed the people in the Law while the people were standing there.8 They read from the Book of the Law of God, making it clear and giving the meaning so that the people understood what was being read.
9 Then Nehemiah the governor, Ezra the priest and teacher of the Law, and the Levites who were instructing the people said to them all, “This day is holy to the Lord your God. Do not mourn or weep.” For all the people had been weeping as they listened to the words of the Law.
From this account it is absolutely manifest that the people of Judaea had never heard or read this Law before Ezra recited it to them. So the idea that "much people of most nations" had been reading it a thousand years before, is utterly ludicrous.
