For MUSLIMS, Qur'an is the ultimate yardstick, but for many non-muslims Science is the yardstick in life.

Many non-muslims say Qur'an is the word of the man, so such proofs are for them to see and understand that it is impossible without divine revelation to give so detailed description about embryology 1400 years ago when science has discovered it not so long ago that too with the use of powerful instruments for the study.

May Allah guide us all to the straight path, aameen.
