The argument is being roughly defined now and here. I will likely offer refinements in later posts.
"The Russell Dome" argument I believe is the single most powerful and persuasive argument and in the end I feel my be either the only argument needed or the final nail. It is to strictly focus and deal with all things "firmament" from genesis 1:6-20. Period. This is the strategy.
The tactics are way too many to list here, but I can get started w some.
- most Christians have a vague idea of heaven, it is precisely defined and located in genesis. This is exactly where their loved ones who passed away and could be one of the lucky 144,000 in heaven/firmament.
- firmament was dome was accepted idea until only recently changed, and modern ideas like outer space must be wrong
