Something Might Happen...

When the sun dies,

They would have dreamt of the past golden days and compare it to that day's pitch black ones. 

Scientists would have invented a new way for producing food,

Then it would have been a time when our body doesn't need Vitamin D anymore.

It might have been a time when carbon dioxide would be needed for our survival,

For our body would have evolved to something that may be alienic to our way of thinking today!

Students would have been taught that machines are called Autotrophs,

And physics would have been about the principle of its working.

Who knows whether this beautiful world of today's would have totally changed!

And the story of our Era would have lied deep under the Earth's crust still undiscovered for grandmas to tell their grandchildren a story "Long Long Ago ......"
