For this debate there is no scientific or historical reason needed as to why you think which is better. But for those who do include research and data as to why one is better, don't be ripping on those who decide not to. Other than that go crazy :) (within reason of course).
I do not think fact can be used to convince anyone in this point, but in all reality, the bounds of a single room can never compare to the bounds of our world. Even in our small lives we can never see it all. From my part no further justification is needed.
