God's word unmistakably teaches a young earth and universe ("the heavens"). God has ensured the accurate recording and preservation of His eyewitness account of the earth's history, which Jesus Christ endorsed repeatedly during His earthly ministry.
God took great care to include the necessary chronological details of the universe's creation in six literal days, as well as the unbroken genealogies of mankind from Adam to Jesus. So we have absolutely no doubt that the earth is only around six thousand years old.
Contrary to Scripture, many geologists claim that radiometric "clocks" show rocks to be millions of years old. However, to read any clock accurately we must know where the clock was set at the beginning. It’s like making sure that an hourglass clock was set with all the sand in the top bowl at the beginning. However, no geologists were present when the earth and its many rock layers were formed, so they cannot know where the radiometric clocks were set at the beginning.
