Darwin's On the Origin of Species gave evolution a boost, but no one is afraid to reject its errors or to improve upon its inferences.
The difference is, TheEngineer doesn't improve on Rowbotham's model at all. He simply states that it is no longer valid without giving alternatives or a reason for why it is no longer valid to FET. I will suggest that he crawl back into his hole until he has something constructive or meaningful to say.
If we are merely trying to "one-up" you, please explain this apparent contradiction (highlighted in bold) in what you stated.
Rowbotam is unclear what exists beyond the edge of the Ice Wall. His assumption is that is stretches on perpetually. From the edge of the Ice Wall, for as far as the eye and telescope can see, the tundra of ice and snow stretches seemingly forever.
TheEngineer, however, changes Flat Earth Theory by unjustifiably stating in the FAQ that there is an edge just beyond the Ice Wall.
If TheEngineer thinks that he can provide a more comprehensive model than Rowbotham, then why doesn't he ever show us this model? Why does he continue to link to Rowbotham? It really is unnecessary for him to come in here with his twaddle claiming that Earth Not a Globe is no longer valid. It's ignorant of him to think that there is an edge to the earth without telling us how the atmosphere stays upon the earth's surface.
It's a simple tactic he uses to avoid having to answer certain questions about Flat Earth Theory, nothing more. Engineer avoids questions by stating "that's not my model, that's Tom's/Robotham's model!" He will then ignore a topic and repeat the same thing next week verbatim. It really is transparent of him.
