We disagree. I led a study of several families on the Foundations series, as well as
ICRs Unlocking series (amazing amazing series). The kids, about 11 and up ate it up, not just the fun science stuff, but the theology. Suddenly they were getting it, from the gospel to everything else. It's all tied into the creation account, and old earth theories frankly confuse matters. I'm not saying no one can get the Gospel otherwise, just saying, it made it a lot easier.
I agree. Romans 14 for those things that are not spelled out. Where we disagree, is whether the Genesis account is unclear. It's as clear as anything else, in my view, and the series of events, in the right order, vivifies the Gospel. Creation (very good), Curse (Adam's sin), Cross (the Last Adam).
