My fault. I actually, did not know because I did some research and opinions say 30 years. Please forgive me.
which was written in the mid-first century CE. And also
also written by Josephus. Josephus lived from 37 CE to about 100 CE.
8. For we have not an innumerable multitude of books among us, disagreeing from and contradicting one another, [as the Greeks have,] but only twenty-two books, (8) which contain the records of all the past times; which are justly believed to be divine; and of them five belong to Moses, which contain his laws and the traditions of the origin of mankind till his death. This interval of time was little short of three thousand years; but as to the time from the death of Moses till the reign of Artaxerxes king of Persia, who reigned after Xerxes, the prophets, who were after Moses, wrote down what was done in their times in thirteen books. The remaining four books contain hymns to G-d, and precepts for the conduct of human life. . .
For it is no new thing for our captives, many of them in number, and frequently in time, to be seen to endure racks and deaths of all kinds upon the theatres, that they may not be obliged to say one word against our laws and the records that contain them. . .
As to the laws themselves, more words are unnecessary, for they are visible in their own nature, and appear to teach not impiety, but the truest piety in the world. They do not make men hate one another, but encourage people to communicate what they have to one another freely; they are enemies to injustice, they take care of righteousness, they banish idleness and expensive living, and instruct men to be content with what they have, and to be laborious in their calling; they forbid men to make war from a desire of getting more, but make men courageous in defending the laws; they are inexorable in punishing malefactors; they admit no sophistry of words, but are always established by actions themselves, which actions we ever propose as surer demonstrations than what is contained in writing only: on which account I am so bold as to say that we are become the teachers of other men, in the greatest number of things, and those of the most excellent nature only; for what is more excellent than inviolable piety? what is more just than submission to laws? and what is more advantageous than mutual love and concord? and this so far that we are to be neither divided by calamities, nor to become injurious and seditious in prosperity; but to contemn death when we are in war, and in peace to apply ourselves to our mechanical occupations, or to our tillage of the ground; while we in all things and all ways are satisfied that G-d is the inspector and governor of our actions.

Josephus and Philo
But it certainly existed before then as well. Josephus lived almost two thousand years ago, around the first century C.E., and wrote his works probably around 75 C.E. Josephus mentions the Torah numerous times, and clearly refers to it as something that had been around a long time. In his work called Contra Apion, he writes:
For we have not an innumerable multitude of books among us, disagreeing from and contradicting one another, as the Greeks have, but only twenty-four books, which contain the records of all things past; which are justly believed to be divine; and of them five belong to Moses, which contain his laws and the traditions of the origin of mankind till his death. (Book 1, Chapter 1, Number
There you have a clear reference to the Books of the Bible, and explicit mention of the Five Books of Moses. This is just one reference of many. Josephus mentions the Torah throughout many of his works. (See, for example, Antiquities of the Jews 4:8:3 and 2:16:5.)
Josephus is very clear that by his time there already existed a book of Laws written by Moses, and that it tells of the stories that Josephus himself tells in his Antiquities.
But was Josephus speaking of something new, or something that was already very old? Josephus was speaking of something that was already considered very old in his time. How do I know? Because he says so. In Contra Apion, Josephus writes that our Sacred Books are very old, and he asserts that no one has ever added to them or changed them in all the years since they were created.
...and how firmly we have given credit to these books of our own nation is evident by what we do; for during so many ages as have already passed, no one has been so bold as either to add any thing to them, to take any thing from them, or to make any change in them; but it is become natural to all Jews immediately, and from their very birth, to esteem these books to contain Divine doctrines, and to persist in them, and, if occasion be willing to die for them. It is no new thing for our captives, many of them in number, and frequently in time, to be seen to endure racks and deaths of all kinds upon the theaters, that they may not be obliged to say one word against our laws and the records that contain them; whereas there are none at all among the Greeks who would undergo the least harm on that account [i.e., for their own books].... (1:1:
So it is quite clear that the Jews had these books, and believed in them, long before Josephus, who lived almost two thousand years ago. The Jews of his time, almost 2,000 years ago, already had all the Written Torah we have today, and believed them to be the originals, just as we believe today.
Let's go back a little further. Philo (around 20 B.C.E. to around 50 C.E.) also talks about the Books of the Torah, in his work The Life of Moses (II:288-91). He also says that the books of the Torah are very old.
The writings of Josephus and Philo both prove that the Written Torah was already composed by the first century of the Common Era.

The Septuagint, Sadducees, and Ben Sira
Let's go back a little more. The Septuagint (a Greek translation of the Torah first written by Rabbis and later changed dozens of times by numerous people), is claimed by the Gentiles to date back to 275 B.C.E. (Our Tradition dates it a bit later, at 245 B.C.E., according to Rabbi Fendel, in Legacy of Sinai, page 136.) So the Written Torah already existed at that time.
Also around that time, the emergence of the Sadducee and Boethusian sects took place. The Sadducees took as their platform the statement that they believed only in the Written Torah, and rejected the Oral Torah. Evidently, at that time both the Written Law and the Oral Law already existed.
So now we know that the Torah already existed by around 275 or so B.C.E. That's 2,275 years ago, as I write this.
Let's go back a little more. Ben Sira (circa 400 B.C.E.) also mentions the Books of Torah, in the same number and names that we have them today. So the Tanach existed then as well, around 2,400 years ago.
2,500 Years Ago
The Samaritans, and the Ten Tribes
We can go yet further back. The Samaritans learned the Torah from the Ten Tribes sometime around 550 B.C.E. So, by then the Chumash and Joshua were already written. Some of the Kohanim of the Ten Tribes taught it to them. Any time after that, the Samaritans would not have accepted the Torah from the people of Judah, because of the Samaritans' hatred for them. So, since both the Jews and the Samaritans have the Chumash, we know that the Chumash had to have been written some time before 550 B.C.E., before the two groups stopped having contact with each other.
This also proves that the Torah could not have been written during the time of the two kingdoms. Since the Ten Tribes taught the Chumash to the Samaritans, that means the Ten Tribes had to have had the Chumash before they split off from the other two Tribes. During all the time that they were split, neither kingdom would never have taken Torah from the other.
Yet the later Books, written by Prophets among the two Tribes in Judah show numerous examples of how the Ten Tribes kept the Laws of the Torah (with occasional lapses), and that they had the Torah (see, for example, I Kings 21:13; II Kings 4:23, 7:3; Hosea 4:6; 8:1, 8:12; Amos 8:5, et. al.).
So, during the time of King Solomon, before the breakup of the nation into two kingdoms, the Chumash must have already existed. But they must have already existed earlier, or the Ten Tribes would never have accepted them. They took them because before they broke off these Books had already been fully accepted by all Israel.

King David
Could the Torah have been written during the time of King Solomon, or during the reign of his father, King David? Definitely not.
Consider what the Torah says about the nations of Moab.
The Torah (Deut. 23:4-7) says that a man from the nation of Moab may never marry a Jewish woman, even if he converts to Judaism. Even the descendant of a convert from Moab may never marry a Jewish woman. This was because of the way they treated us when we passed near their land on the way to the Land of Israel. They did not come forward to offer us bread and water, as was their custom. The women of Moab, however, after conversion to Judaism, are not forbidden to marry a Jewish man, because it was not the custom of the Moabite women to meet travelers with bread and water, and also because they had no connection with the attempt to curse Israel.
