Sense Sonnet - Steamer

Billion in Time

A billion years ago - Earth formed,
And was rotating the sun.
A billion days ago there stormed
Ice ages across U.S. run
A billion hours ago man
Came to the U.S. primitive.
A billion minutes ago ran
The first Christians seeking to live.
A billion seconds ago sent
U.S. troops to Korean War.
A billion in time came and went.
A billion ago seemed much more.

A billion dollars ago - hey!
U.S. Treasury spent today.
