As a member of the non-Creationist laity, I hope that it is of value for the likes of myself to contribute to some of these dicussions, to show that even if you don't have an in-depth knowledge of science and specific data, you can still understand the principles and logic that make the scientific case so strong and reliable.
Yes and no... Generally, sure, you don't need a lot of in-depth knowledge.
But this guy was talking about atmosphereic levels and decay rate changes of carbon 14. It going to take some in-depth knowledge to get it with that one, its not something your just gonna hash out for yourself with reason and common sense.
I'd be interested to know if scientists on this site appreciate contributions from the likes of myself on these topics, arguing mainly out of reason and common sense (I hope)...
Yes! The more the merrier!
