Peacefulpete is merely describing what we learned in our Catholic catechism and what you find in Protestant study Bibles and commentaries
Watchtower teaches Biblical literalism. That what you read is historically true at face value.
Yet the Bible writers used different genres to preserve and pass on their truths. They often employed motifs familiar to the ancient reader. This meant borrowing from popular types and formats of ancient storytelling
While they were sharing "truths," they wrote these using these ancient genres: mythology (origin stories), legend (popular tales), and folklore (oral history of peoples and cultures). We don't use any of these to tell true stories today, but they did in the past
Like the Moses story, where as a babe, he is preserved from pharaoh by being placed in a reed basket and sent down the Nile only to be discovered by Pharaoh's daughter. This is likely not history but a borrowed mythological motif which ancient readers would have immediately recognized as a common theme or indicator used in stories about people chosen by the gods for an important destiny.
The same thing happens in the story of the Sumerian king Sargon I and the tale of Romulus and Remus. The author of Exodus is likely using this same mythological motif, not because they are lying but because they are trying to tell a truth that in reality cannot be put in common words. If you don't know the mythology, you miss the truth the writer is saying which isn't what you read at first blush
In reality how does one describe being chosen and destined by God with all that that truly means? How do you explain Jesus if he really did die and rise from the dead? The Bible writers did not rely on literal forms of expression because the ancients were more complicated in their processes with preserving what they believed were truths. Can you really just say that someone merely died and his body was not there when you looked for it later? That doesn't tell or teach me anything, especially if my eternal life is at stake
We cannot say they were literal facts as measured by today's standards. But they were not asking us to. They wanted us to use their standards. And often that means using and appreciating myths, legends, and folklore
