And almost all of people still think Venus being a planet.
Because it still is one?
And according to your reasoning, using results from my google:
Number of Jesus believers: 2,200,000,000
Search to jesus: 1,140,000,000
Search to water: 8,450,000,000
Number of water believers by using ratio:
2,200,000,000 x 8,450,000,000 / 1,140,000,000 = 16,307,017,544
So twice as many people than exist believe in water.
Looks like your method is still horribly broken.
We have to focus on the reasons of people are leaving the flat earth theory.
Or you have to focus on why your methodology is so fundamentally flawed that it isn't actually calculating the number of believers.
On the other hand, nasa believers have decreased too. And belief on flat earth is still more than nasa belief.
Even if you want to use your excuse, NASA and Flat Earth are not in the same category and thus your method cannot determine the number of believers. As you have made clear, FEism is a religion, comparable to other religions like Christianity. It is not an organisation like NASA is and thus you cannot compare the 2.
