I don't believe that God hides Himself in creation; I believe He is manifest in it.
For ever since the creation of the world His invisible nature and attributes, that is, His eternal power and divinity, have been made intelligible and clearly discernible in and through the things that have been made (His handiworks). So [men] are without excuse [altogether without any defense or justification], because when they knew and recognized Him as God, they did not honor and glorify Him as God or give Him thanks. But instead they became futile and godless in their thinking [with vain imaginings, foolish reasoning, and stupid speculations] and their senseless minds were darkened. Claiming to be wise, they became fools [professing to be smart, they made simpletons of themselves].
--Romans 1:20-22 (Amplified Bible)
I also believe that the Bible is intended to be a book of spiritual truth, and as such, it's pretty good at being what it is intended to be. If someone tries to use it in a way that it was NOT intended--like as a science or history book, for instance--they are likely to fare much worse.
Now anthropology isn't any particular interest of mine--I can barely stand MODERN history--but I treat it like any other body of scientific knowledge; i.e., the best that we have so far. To the extent that the Bible conflicts with scientific or historical (including anthropological) knowledge in matters of science or history, I will defer to science and history. To the extent that science or history conflict with the Bible in matters of spiritual truth, I will defer to the Bible.
