Is it possible that Earth is Flat?

We're not just going to roleplay, we're going to live out all of these questions like they're reality. We're going to treat the world like everything is a huge lie. We're going to pretend that the powers-that-be maybe lying to us all and hiding a huge secret like the Earth being flat. What is the possibility that the Earth could be flat? What is the likelihood that the Earth is either larger than we know or that the entire thing (science) is a lie. What if, just, what if! What if the Earth is flat? What would change? What things would stay the same and what things would get turned on their heads after we all found out the truth regarding the real shape of the Earth. Who would reveal this news? Who and/or what government or religious entity would be in charge of breaking the news to the world?
