How can they get there if they don't have a map ? They can't even agree on which map to use and some of them say there is no map.
Well when they encounter an impossibility of something they just go ahead and deny it, including their own map, so not a big big bummer cop-out poopy there. But in any case, they do not necessarily NEED a map to get to the edge of the earth, just as you do not need a map to get to the edge of water on an island. Just go any friggin direction and keep to it.
On the other hand, it's way easier to parrot "have you seen a satellite with your own two eyes" type of demogogical polemic on internet forums to go on touting a religilous blind bat belief, as opposed to buying a 20USD compass, renting a dingy boat and start sailing f:n west from california.
Now why would I need to see a friggin satellite with my own two eyes when I see millions of dishes staring up at the sky to receive satellite TV all over the world dear flatters? Why? Let's start talking about some heavy-duty conspiracy here!
