In the good old days when I used to have a seminar on this topic that I used in churches, I had an overhead transparency that showed the age of the earth (along with some of the various geological time periods). This was represented by a line that went the length of the slide. Beside it was the young age, represented by a dot.
The BioLogos Foundation Science and the Sacred blog has something about this today. It’s not a minor difference, explainable by slightly different interpretations. It’s a massive. fundamental difference.
