Actually, it is you who feels the need to defend a 6,000-year-old earth, treating 2,000-year-old writings as 100% accurate and final. It is you who will not change that position, no matter what new evidence, observations, or evidence arises. Can you imagine if that type of thinking was applied anywhere else in life?
Conversely for science, the estimated minimum age of the earth has increased, (changed), several times over the past 150 years, as new discoveries and observations were made. Lord Kelvin theorized that the age of the earth was between 20 million and 400 million years. That was back in the mid-1800’s.
I feel the need to teach students the most updated and accurate information, and with enthusiasm! I feel the need to teach students the closest explanation and understanding of reality, and how our world works.
The magnitude of error of the 6,000-year-old earth model is so great, it is the equivalent of claiming that a mere 25 feet separate New York and San Francisco. It boggles the mind.
