The Bible doesn't specify the exact age of the Earth OP.
>Has anyone tried this?
Yes. Sir Isaac Newton (You know, single smartest man who ever lived? Yeah, that one)
was the first scholar who made a concerted effort at answering your question.
His answer? We don't know from the Biblical text. It is indeterminate.
While I doubt many other scholars can hope to match his effort on the topic, we do
have writings of the Church fathers. While very little was specifically written by them on this topic by relative volume of text, one thing they did
affirm that has bearing on this question is to affirm the concordance
of God's two books. Namely, the specific revelation of the scriptures, and the general revelation of the 'book' of nature. The creeds confirmed this perspective, and in particular the 2nd of the Belgic Confession
from the 16th century affirms this perspective.
Psalms 19 is a well-known passage that affirms the concordant view.
While the Bible clearly isn't intended to be a science book, much of it's content touches directly on scientific discoveries since it was written. For example, the direct concordance between the creation accounts in the old testament (Genesis chapter 1 being the most well known of a couple dozen passages) that revealed both the singular origin of the entire universe (aka "The Big Bang"
), and also the character and evolution of the earth, the stars, the sun, the moon, the oceans, and the land. Of course it also describes the sequence of the creation of life on earth, land, sea, and air. And finally culminating with the highest form of natural creature, we ourselves.
The Bible outlined all of this many thousands of years before
the modern scientific endeavor ever began. Certainly that fact is quite provocative, and suggests the supernatural origin of the book's writings.
