can anyone answer my other questions? 
k forest gump.. we'll answer them backwards one by one and see if you can answer the 1st one by yourself.
"6. Does this all stem from some strong religious belief's?"
i would say the contrary..
i dont know anyone from or am part of the flat earth society, so i dont know what they think in truth, but i know that there is a posibility for the earth to be something different from a sphere, there has been alot of scientific findings in the last decades to put our earth in many different perspectives, we use a globe to represent the earth so we can understand certain 3D or round qualities to it wich it has but is not limited to. soon you will find that looking at the earth in a 3d pespective will be out of date, there are much more things to consider to a round earth than you think.
religion is an organized state of belief, to tell you the truth i dont think any religion in the world is orginized at the moment, they are just maintaining an illusion of orginized.
but belief is something we all have and it doesnt have to be organized into 1 religion for people to co-exist, and that is the root of this forum i belive. to make people aware or to help bring that awareness to people that we (humanity) are able to work together or respect one another no matter what the person decides to belive in.
