For the moment, let's say someone would take more notice quoting those persons rather than the words in the Bible. But then, taking notice of this, two things come to mind (my mind, not necessarily your mind --
-- our minds are in our bodies and are different) -- Genesis says, "In the beginning." That more than suggests that there was a beginning. I don't know how you would take it, but I can compare it to something like Michelangelo's sculptures, and someone describing his artistry. So one could say, "In the beginning, Michelangelo started carving small statues." So what's the beginning referring to? Anyway, I'll be curious as to your answer.
The second thing I was thinking about was when Moses appeared before Pharaoh. Moses wrote down his experience. God conversed with him. But Pharaoh clearly wasn't going to listen, even though Moses said God spoke to him and told him step by step what to do. So Pharaoh and his men found out the hard way that what Moses said was true. Now then, you gotta figure what is true? Some say that Israelites never existed in Egypt. They almost swear by it. Others claim that Jesus never existed. And so -- what do you conclude? I conclude that each one is drawn out by his heart and mind. Even if different persons have different opinions.
