What is Islam?

Being able to comment on the work of the top embryologist requires advanced knowledge of embryology. He has written the article after meticulous investigation and experimentation. To counteract that would require similar or even higher level of effort. Just calling something �vague� that you don�t understand doesn�t mean that the theory is necessarily wrong. It only means further study is required to study the theory."

OK, lets move very slowly.  The Ptolemaic model of the universe, which is generally regarded as the start of astronomy was an Earch centered model.  That is it put the Earth at the center of the universe and had the planets and the sun revolving around it in there own orbits in epicycles.  This tortuous system was used because it explained previously unexplained observations like retrograde motion and changes in planetary brightness.  We can go back even further than this to see the first inklings of Earth centered thought but for now this will suffice.  Now, as you can see, this system had the sun orbiting about the earth in about the first century of the first millenium.  So, as you can see, your statement that the Quran predated the modern discovery of solar motion "more than 1400 years ago without any advanced astronomical instrument of the modern science" is not really accurate at all.  The solar motion that was observed in 1785 by Herschel was the motion of our entire solar system through space.  I hope this is not what you are trying to say these Quranic verses actually indicate because that would stretch my imagination to it's breaking point.
