Chance

With indisputably true suppositions
The atheist scientist makes observations
That bolster belief in a cosmos of chance--
A theory the "fittest" alone can advance

To deceive humankind that God has repressed her--
What name does he give to our common ancestor?
What name can he give to his fair Evolution,
Selecting the best for the next generation?

Perhaps if more fit, he'd be more scientific 
Than to give the name Chance to his quite unspecific
Philosophy, knowing that Chance is like Luck--
Neither can make his primordial muck.
