The graph is not what the debate is about. What is pertinent is whether numerology and the graphing of the results can show evidence that atheists can not refute.
That doesn't come across in the OP, though. You are referring in the OP to a specific argument that atheists may or may not find irrefutable. Are you wanting to debate assuming that the numerology performed does actually create a straight line?
That is to say, are you asking the good members here that if it is indeed true that biblically mentioned colours are numerologically proportional to the frequency of light of those colours would this, as claimed, be the ultimate atheist stumper? Or are you being more general, and asking whether any numerology dataset could be a stumper, giving Shore's work as a mere example? Something else?
Why is the actual graph important? According to what has been said about it it is a straight line.
Supposing it actually isn't despite the claims of Shore...would this be a valid avenue of debate in this topic?
