Very interesting to see what you are comparing God's Word to.I like the Chinese one the best - you can make a gourd into anything! Just think if they had duct tape - they could have traveled to the moon.
The writers were inspired by the Holy Spirit, but that does not mean that the Holy Spirit stole their human knowledge. These writers lived thousands of years before Christ was born. They were ancient people who know very little about their world. When Christopher Columbus wrote in his journal that he reached Asia, does this mean that he actually reached Asia? We already know that he never got there. It is the same with all people who lived in the ancient world. The message that God told the sacred author is not to be ignored. That message is simple: the wicked will be punished and those who are not wicked will be saved. That was the message that God wanted to convey through that historical local flood. In the Old Testament, God revealed Himself through Jewish history. In the New Testament, God revealed Himself through His Son, Jesus Christ. We would look at Jewish history to find God's message in it. And in Jewish history, the ancient Jews did not know that North and South America existed.
Genesis is the Word of God, not opinions of sinful humans.
