Like Fish in the Sea

Like fish in the sea we need
To focus on the here and now.
Why conjure up a theory
For a more abstruse reality?
Still, beyond the sentient clues
Persists a nagging inquiry
What is this sea sustaining us
That breeds uncertainty?

Many people now agree
We have no higher destiny
That life is without purpose
That God is an invention.
Then how do we explain away
Transcendent aspiration
Historically exhausting
Every means and all proficiency?
