Ice cores

I used to be terrified by ice cores.  Do you know ice cores? Each year a new layer of snow and ice is laid down in Antarctica, and scientists have been able to bore down and remove cores of this ice that are 3 km long.  The ice is in layers, and the layers mark years.

The cores are very accurate gauges of time.  For example, we know in which years certain major volcano eruptions occurred.  Find the ice core layer that matches that year, and you’ll find volcanic ash specific to that volcano.  Also, we know how the Earth’s orbit has changed over the years and how those changes alter the Earth’s climate.  These climactic changes are evidenced in the ice cores.

Doesn’t sound too scary, right?  The problem was, I believed whole-heartedly that the Earth was 6,000 years old.  The ice cores give us a climactic record for over 700,000 years.  I could never resolve the discrepancy.  I’d chalk it up to “appearance of age” (The idea that God created the earth 6,000 years ago, but He made it appear to be much older.) and push it under my mental rug.
It was so freeing to me when I discovered that the Bible does not say that the Earth is 6,000 years old.  I learned that the word translated “day” in the Genesis creation account can also mean “a long, but finite period of time,” so God did not create the Earth in 6 24-hour days, but in 6 long eras.  Examining what I had been taught about the age of the Earth was a painful process, to be honest, but it was also liberating.  For the first time, I was able to reconcile the picture of creation God gives us in the Bible with the picture of creation he reveals in the natural world — even in ice cores.
