This statement is certifiably untrue. The Bible describes events which supposedly happened in our world at specific times. They either happened, or they didn't. That's not a "secular point of view" unless by "secular" you mean "reality based." That is not a position you want to try to defend. And in fact, I'm not aware of any Apologist who ever has.
If the Hebrews claim to have wandered around in the desert for forty years but left no trace of their passing found by archaeologists, we have an obligation to regard their claim as untrue unless we can determine some reason why all trace of them would disappear from a particular period in history. That's not a matter of faith.
By secularism I mean operating on the premise that God doesn’t exist.
Think of it this way: the Bible is either logically coherent or not. But it is impossible to demonstrate logical incoherence by using extrinsic arguments.
In the case of the Bible, an extrinsic argument is one which operates on the premise that God doesn’t exist. It is circular reasoning and therefore invalid.
