For example, during the Red Bull Jump, Felix was up 128k feet and it seems so dark.  I am new to the flat earth theory - but even then I thought "wait, how is it darker up there than it is down below on earth if the sun is 95 MILLION miles away .... Shouldn't all of space be brightly lit"  This has always baffled me.  So - if the earth IS flat and our sun and moon are local to us ....how far up ARE they? and ....why is it dark(er) at 128k feet???
