It's not poetry!I didn't say determines.
I said if you're interested in seeking the truth.
When you ignore literary style you will sabotage any effort in searching for the truth.
If you read 'Lord of the Rings' as a historical account you are really going to fool yourself about the truth of history.
If you read 'Journey to the Center of the Earth' as a scientific report, you are going to be dumber than before you read the book.
If the read 'Genesis 1' as scientific literature you are ignoring it's purpose as poetry.
