Atheists....?

this is a verse from Holy Quran about embroyology and you tell me how some one other than God wouldve known this 1400 hundred years ago. "Subsequently, we produced him from a tiny drop, that is placed into a well protected repository. then we developed the drop into a hanging(embryo), then developed the hanging (embryo) into a bite-size (fetus), then created the bite-size(fetus) into bones, then covered the bones with flesh. we thus created a new creature. most blessed is God, the best creator, then, later on, you die. then, on the day of resurrection, you will be resurrected. [Quran 23:12-16]. Embroyologists also agree with this verse.
