First of all I would like to begin w/ two points on which I hope we can agree. If you have problems w/ these points, please discuss that. If you discuss the things a bit further in I will assume that you agree w/ these points.
(A) There are observations/evidence that, at least when taken at face value, support a Round Earth (i.e. photos from space). There are observations/evidence that, at least when taken at face value, support a Flat Earth, (i.e. "Earth not a Globe")
(B) If you believe in the standard FE model, than you cannot say w/ any degree of certainty that the motivation for the Conspiracy is money. Why? Because to do so you have to assume that what NASA is being truthful about their finances. As NASA is lying about everything, there is no reason to suppose that they would be truthful in this one area. Now, financial motives are likely, but to say that NASA is doing it for the money is just speculation.
Now, I shall outline two Scenarios
(Scenario 1) All of the evidence that seems to point to a Round Earth is the result of fraud, misinterpertation or error. The evidence that points towards a Flat Earth is largely correct.
(Scenario 2) All of the evidence that points towards a Flat Earth is the result of fraud, misinterpertation or error. The evidence that points towards a Round Earth is largely correct.
So, any FE's wanna give me any reasons to prefer (Scenario 1) to (Scenario 2)? You believe (Scenario 1) so I'm going to go out on a limb and assume that you have some reasons to do so, and go out on another limb and assume that you might like that share those reasons. I realize that's alot of limbs, but what the hell.
Remember, that you can't reasonably ascribe financial motives to NASA.
