"We have as much evidence for the actions of ancient Biblical figures as we do for ancient historical figures."
.
Uh, no.  Not so much.
.
There is certainly Archaeological and textual evidence that many individuals identified in the bible existed as a matter of historical record corroborated by other sources.  True enough.
.
But the converse is not true.
.
The bible gives no information on 5000 years of Chinese history, or Indian history, or Japanese history, or Norse or Gemanic history, or the history of the Americas, or of the history of Africa, and the people who lived in those places.
.
It does not even cover the pre-Christian history of Troy, Athens, Sparta, or, largely, Rome.
.
The actual historical record, incomplete as it may be, is vastly greater than the sagas of one set of tribes in the fertile crescent recounted in the Bible.
