How old is it and who discovered it? was it god who wrote it?

You asked "who discovered it?"
This might help.
2 Kings 22:1-13 (King James Version)
1Josiah was eight years old when he began to reign, and he reigned thirty and one years in Jerusalem. And his mother's name was Jedidah, the daughter of Adaiah of Boscath.

2And he did that which was right in the sight of the LORD, and walked in all the way of David his father, and turned not aside to the right hand or to the left.

3And it came to pass in the eighteenth year of king Josiah, that the king sent Shaphan the son of Azaliah, the son of Meshullam, the scribe, to the house of the LORD, saying,

4Go up to Hilkiah the high priest, that he may sum the silver which is brought into the house of the LORD, which the keepers of the door have gathered of the people:

5And let them deliver it into the hand of the doers of the work, that have the oversight of the house of the LORD: and let them give it to the doers of the work which is in the house of the LORD, to repair the breaches of the house,

6Unto carpenters, and builders, and masons, and to buy timber and hewn stone to repair the house.

7Howbeit there was no reckoning made with them of the money that was delivered into their hand, because they dealt faithfully.

8And Hilkiah the high priest said unto Shaphan the scribe, I have found the book of the law in the house of the LORD. And Hilkiah gave the book to Shaphan, and he read it.

9And Shaphan the scribe came to the king, and brought the king word again, and said, Thy servants have gathered the money that was found in the house, and have delivered it into the hand of them that do the work, that have the oversight of the house of the LORD.

10And Shaphan the scribe shewed the king, saying, Hilkiah the priest hath delivered me a book. And Shaphan read it before the king.

11And it came to pass, when the king had heard the words of the book of the law, that he rent his clothes.

12And the king commanded Hilkiah the priest, and Ahikam the son of Shaphan, and Achbor the son of Michaiah, and Shaphan the scribe, and Asahiah a servant of the king's, saying,

13Go ye, enquire of the LORD for me, and for the people, and for all Judah, concerning the words of this book that is found: for great is the wrath of the LORD that is kindled against us, because our fathers have not hearkened unto the words of this book, to do according unto all that which is written concerning us.

I don't think that the Bible existed before this time.
Hilkiah the high priest and Shaphan the scribe, began writing the Bible and passed it off on the 26 year old King Josiah as a very old book from God and King Josiah believed them. When you think about this, with an open mind, you realize how preposterous it is that the story of Moses and the Law Covenant with God could possibly be lost and the High Priest Hilkiah just happens to find it in the temple.
What a con job.
But then people today still believe this ridiculous story.

The "Book of the Law" is a reference to the book of Deuteronomy.

When Joshua referred to "the Book of The Law", do you think that he was referring ONLY to the book of Deuteronomy or was he referring to the complete Torah, the five Books of Moses?

Joshua 1:8 (King James Version)
8This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success.

Do you expect that Joshua was only concerned that Israel meditate and observe ONLY Deuteronomy, and forget about Genesis, Exodus, Leviticus and Numbers? Or was Joshua concerned about the whole Law contained in the complete Torah, The Book of the Law?

Thanks Stuart Shepherd yeah that helps

Well, the thing is the bible didnt come into existence until about 1600-1800 years after the first scriptures were written. About 400 years after Jesus' death. It's a collection of scriptures that were put together to make a book. It's like someone today taking short stories with similar subjects and themes, and then publishing them into one book. So that means nobody really "discovered" it. Then it went through additions/subtractions of scriptures, debate, and translations.

If you have A LOT of time on your hands, try reading this essay: The Bible and Christianity

-Rhem

As metis already pointed out, book of the law means the book of Deuteronomy, not the entire bible.
