Fresh Fossils

Now I'm walking on the beach I came to understand
With each step I left a footprint, a fresh fossil in the sand
Looking over my left shoulder, behind lay my old track
And I will be my old man, Friday or whenever I came back

Up ahead I saw the future, a streach of barren beach
I knew that I was heading nowhere, the horizon out of reach
So I turned and headed back, I was present in my past
Now and then mere twin directions, the next intersecting the last

There was proof that I had been there, and proof I'd come and gone
Inprinted in the sand's a time so why should I walk home
Now and then I'm gonna go though then I'm not the same
And future waves with araised both as if I never came
