It really doesn't matter that your argument is completely illogical. Either way according to your book, the almighty creator gave us false information about to shape of the planet we live on. It doesn't matter that we weren't according to you "ready for spheres". He's all powerful, yet he couldn't tell us that the Earth was more or less shaped like a ball. Even though that is still false because it isn't perfectly round. It doesn't debunk your "original point" because you had no point in the first place. Your entire argument is based off of what shapes people could understand back in the day. Even though the ancient greeks were thriving hundreds of years before Christ, and they understood round objects perfectly fine.
