Why are these called "The All"? Based on the sutta quote below:


Why are these called "The All": the eye &amp; forms, ear &amp; sounds, nose &amp; aromas, tongue &amp; flavors, body &amp; tactile sensations, intellect &amp; ideas?
Why someone trying to explain "The All" as being something else would fail?
What does "it lies beyond range" mean?


From Sabba Sutta:


  "Monks, I will teach you the All. Listen &amp; pay close attention. I will
  speak."
  
  "As you say, lord," the monks responded.
  
  The Blessed One said, "What is the All? Simply the eye &amp; forms, ear &amp;
  sounds, nose &amp; aromas, tongue &amp; flavors, body &amp; tactile sensations,
  intellect &amp; ideas. This, monks, is called the All. Anyone who
  would say, 'Repudiating this All, I will describe another,' if
  questioned on what exactly might be the grounds for his statement,
  would be unable to explain, and furthermore, would be put to grief.
  Why? Because it lies beyond range."
Buddha's time in India there were many views about the world. This is similar to saying nowadays "The all mighty God" etc. These views are discussed in the Brahmajala Sutta. These wrong views lead you to a wrong destination. However, according to Buddhism the right view lead to Nibbana.
What Buddha saying is nobody can comprehend anything beyond six senses.
