i love when complex things are broken down to its simplest form. Makes it easier to comprehend for some.
That way, they dont have to actually think about the "why", just say "because it is"
for instance, you say "the sun is hot". We all know the sun is hot. Because we feel it when the sun is shining. The closer the sun is to earth ( summer) the hotter it feels.
Thats simple.
But WHY is the sun hot? What makes it hot?
