Hi vimesey,
If I can toot my own horn (even with several of my topics already listed
), except as noted (these are topics that interested me enough to create or read\participate):
Age
Origins\Abiogenesis
Biology
Geology\Fossils
That first one is possibly the longest running thread on the forum, having been updated and reposted 4 times, and now running to 964 posts, but you don't need to read the earlier versions ...
On closed threads I would go to the end to see if there are summary posts (a fairly recent addition to ending threads that lets each poster on the thread make a summary of their position/s, so you don't have to read the whole thread unless you want to see how these develop in the course of the thread)
Enjoy
