The mathematical genius and credit to humanity, Archbishop James Ussher, determined with thereafter-unchallenged finality, in 1647, the exact age of the Earth based on the lineage documented in the inerrant word of God, the Bible. In the beginning, God created the heavens and Earth on October 23rd, 4004 BC (having started cooking the whole brew the night before), making the entirety of existence exactly 6013 years old today. This just so happeend to have occurred exactly four thousand years before the Bible-scholar’s agreed-upon year that Christ was born. This calculation is based upon the unbroken documentation of the lives and birth years of every generation of human existence from the moment of creation, through the Great Flood which shaped our planet’s current geology, through until the reign of Nebuchadnezzar II, whose empire reigned in 586 BC. Obviously, therefore, any so-called “evidence” of an old Earth was placed here to test our faith in the inerrancy of the word of God, by either the devil, or by God himself, depending on who you ask.
And religious types say atheists are arrogant in looking at physical evidence to make determinations about the state of this universe, rather than merely accepting as absolute truth a book whose provenance is as specious as its truth-claims. Sigh.
