The embryology stuff (Surah 22, yes?) is broadly right, but so what - other secular accounts starting earlier had similar levels of knowledge. Cutting dead people up allows you to do that. Nothing it says is any sort of sign of anything supernatural, merely the possession of a few knives and the ability to describe.
18:86, 90 supports a flat earth: "When he reached the setting-place of the sun, he found it setting in a muddy spring.... Till when he reached the rising-place of the sun." & "Till, when he reached the rising-place of the sun, he found it rising on a people for whom We had appointed no shelter therefrom."
71:16 says: "And hath made the moon a light", which suggests it is it's own source rather than a reflector and therefore goes against what you're claiming.
12:4 says: "When Joseph said unto his father: O my father! Lo! I saw in a dream eleven planets and the sun and the moon, I saw them prostrating themselves unto me."
Far from us getting closer to 11 planets, we've just declassified Pluto.
Not quite the hotbed of science you would have it...
