I can't help you regarding the Qu'ran, since I'm not that familiar.
I appreciate your question, however, regarding the Bible. I think the important thing to keep in mind when you're reading the Bible, is that it is a historic document written in many different genres, as well as a religious text. Just as a book of poetry uses images and metaphors, so the Bible uses them freely, intertwining them with historical narrative throughout the entire Bible. Just because the word of words used to illustrate the principle are simple does not mean that they are altogether incorrect. If you read the Old Testament alongside ancient texts from that time - I'm referring to Egyptian, Ugaritic, Babylonian texts- many of them describe the natural world in terms of things they know.
This is not unfamiliar to even several hundred years ago, when the world was imagined as flat, water pouring off of either side. They were operating from what they knew, not what WE know.
Their understanding of the world and the way they wrote was influenced by their culture. Israelites were farmers, sheepherders, and carpenters, so they wrote from their particular contexts. But they were also deeply religious, and deeply philosophical, and the books - in addition to somewhat simplistic observations of the natural world - also contain some amazing philosophical teachings (especially in the New Testament, Matthew 5 for example).
Even some of the classical philosophers that Athiests and Ignostics so admire were completely wrong in their understanding of Cosmology, or how things came to be. We don't fault them for it, because they did not have the modern conveniences and advancements that we have, so they could not observe the world in the same way.
But in terms of what the Bible is able to teach and communicate about the life and ministry of Jesus, I don't really think any ancient text parallels it. What Jesus taught changed the world - in his day, and continuing on into today.
You may not agree with the Bible's account of creation, or the way they interpreted the natural world around them thousands of years ago, and I think that's just fine. I don't think that it conflict in any way with the overall message of the Gospel, and the importance of the teaching of Jesus.
But thanks for your question - you obviously have a very intelligent mind with a thirst for truth, and I hope it leads you to some answers.
