I'm sorry, but that is simply not true. I happen to be a biology student, and if I was required, for example, to try and make a discovery of why *something* causes cancer at a genetic level, I am going to need background knowledge on DNA, sequencing methods, molecular kinetics, etc. What your arguments are suggesting is that I need to dispute all of that science because I have not formed any of the conclusions myself. So basically, I need to re-discover the cell, re-discover DNA, re-invent a sequencing method, etc, etc... which means I will never come to any new conclusions. Science works by building on the work of others, that is a fact. IF you have a good reason to dispute a previous scientific claim, then that's fine. As of yet, I see no collection of evidence that supports flat earth theory over round earth theory, which is why I (and most intelligent people) choose to believe what has been written in text books regarding round earth, because there is CLEARLY much more numerous and logical pieces of evidence supporting Round Earth.
