Universal puzzles

In this universe is everything,
As rudimentary; as is a sum?
As 1 + 1= 2
Are the building blocks of life?
So profoundly, complicated
As E=mc2 is, or was at first to gist.
My guess is it’s not, so why
Do we need a lightning bolt?
A falling apple … on our head
Is it as linear as we’re supposed to think?
Well string theory has got me all raveled up.
So what do you think?
