Sean, I know you are of the Christian faith. I suggest you check out Rob Skiba's website and YouTube (if you haven't found them already) as he has looked at this extensively from a Biblical perspective. Been reading your site for years and very glad you are opening up to this!

Also on YouTube: Mark Sargent, Jeranism, ODD TV, Allegedly Dave, etc... Enjoy!

I checked out the site you referenced, great info, I watched a 6 hr video on the site, that answered several of the questions I had for flat earth theory. Not sold yet but it makes you think. (upvoted)
