The old testament had an ending, it ended. Went from constant characters and events, world shattering, nation beginning/ending, bigger than life itself, dramatic... everyone knows these stories believer or not, read the bible or not.
But it ended, the biblical story of thousands of years stopped.
The new story was contained in 33 years, the biblical records were written in less than 100 years.
The bible itself stopped after that time, when before it was an ongoing continuous record of God and man.
God/man relationship was changed, worldly events and characters are no longer worthy of biblical inclusion.
