I highly recommend watching Illuminations sometime and focusing in on the globe and what is going on on the screens, and listen to the words of the song when that part comes. That is where you will be able to really "see" and hear the story. The globe, along with all of the fireworks, lights, music, and lyrics, are telling the story of Earth and humans. That is why it is called "IllumiNations: Reflections of Earth".
Illuminations begins with the Creation/Big Bang (it can be seen as either - your choice). Fireworks, fire, explosions, etc. It is all very orange and white.
Then the planet begins to form and cool, and that is when you see the globe come out.
As it cools, it goes from blue (water) to green (land). The fountains are also emphasized here.
Eventually, you see animals and people appear on the globe.
After the people appear, you start to to see the creative side of humanity. Even the fireworks become more colorful. There are segments on transportation, art, architecture, music, specific historical people, and so on.
Then there is the part about getting along, and the finale and the Promise/We go on song:
Every evening, Brings An Ending
Every Day Becomes A Legacy
Every Sunset Leads To Morning
With The Promise Of Opportunity
We Can Reach For The Stars We Find Along The Way
Dreaming As We Learn To Love Everyday
Promise, You Will Take My Hand
As tomorrow Comes, We'll Go on
We'll Go On, Growing Closer Through The Years
Moving On, Through The Good Times And The Tears
Ever On, Another Thousand Circles Round The Sun
If Two Can Be As One, We'll Go On
There Is Music, If You Listen
In The Rhythm Of Each Breath We Take
Destinations Undiscovered, Revelations From Every Choice We Make
And I know, There Are Diamonds Dancing In The Sky
All We Have To Do, Is Open Our Eyes
Promise, We'll Walk Side By Side
As A New Day Dawns, We'll go On
We'll Go On, Growing Closer Through The Years
Moving On, Through The Good Times And The Tears
Ever On, Another Thousand Circles Round The Sun
A New Life Has Begun, The Two Of Us As One, We'll Go On
Moving On, Through The Good Times And The Tears
Ever On, Another Thousand Circles Round The Sun
A New Life Has Begun, When Two Of Us Are One
And We Live To Keep The Promise, We'll Go On
Ever on, We'll Go On
This will sound silly to some, but to me, when IllumiNations is looked at as a whole (music, fireworks, fire, water, story, images, architecture), it is a wondrous work of art.
