So you are saying that all the governments in the world agreed on this one thing that everyone will lie about shape of earth. They can't agree on any other topic but shape of earth is such a huge topic that everyone put their differences aside and said, we got work on this together. And to what end? /s

This is a sorry state of our education system. I worry for the future of this world. There better be a more intelligent alien race out there otherwise we are done for.
