Genesis was written by someone who didn't know that the Earth was round. If Genesis mentioned DNA or microscopic organisms, I'd be intrigued.
But it's written in a fashion that is completely parallel with a Bronze Age understanding of the universe.
I'm sure "Bronze Age" folk would've been highly impressed had God used more acronyms in His revelations.
Fortunately for them, God is a better communicator than most. His description of the roles of man and woman in Genesis are timeless and enduring. While Moses' contemporaries might not have understood the details as do you and I, God's affirmation that when man leaves parents to cleave unto woman the result is 'one flesh' has quite naturally stood the test of time...and science.
A definition quite understandable to the relatively ignorant while not at all at odds with modern genetic research...divine revelation is a wonderful thing.
If Genesis mentioned DNA or microorganisms, the words would not have any known translation. Those are modern words which, if a language had them thousands of years ago, would not have had any counterpart until now. And then, how would we know what they mean now?
Those words would be like the word *Selah* in the Psalms.
