Millions of people still believe in that in 2018... This is sad, but there is nothing much that can be done against conspiracies. If you are not against it, you are summed to be part of it... ;)
For the flat earth business, please have a look to @kerriknox blog. It is really good and you may like it :)
I just did, and I liked the way the facts are presented on the blog. I guess there is a conspiracy theory for virtually all explainable event on earth. People are so suspicious of the government, and sometimes the big pharma, that they sometimes overstretch their imagination. Some even argue the moon landing was CGI and I wonder where we got the technology to perfect such in 1969!
It is good to question everything, but at some point, we must surrender with respect to evidence... ;)
Well, that is another interesting way to look at it, without questions we may not be where we are in both innovation, science, and technology. But in the face of all the evidence, we still have diehard flat-Earthers. It is indeed strange.a
Yeah... Not much to say to that... This should be in the human nature :)
