This Is How A Road Gets Made

This Is How A Road Gets Made
Somebody walked on a virgin (land)
Someone else saw their tracks and followed them, leaving a path
It seemed as though I were looking down the hill when I first saw it
But, as I waled on, I realized I was going up

Somebody whistled behind and turning round, they seemed far below
Then I came to where there had been a fire and was shaded
From the sun by the trees
Figure of eight. It's our year, it always was
Credentials:
Made of earth
Drinks water
Breathes air
Makes fire
