So the scientist had conclusion to there is no plan ?
so there is no creator ?
so who made the plan reproduction ?
human science is limited because there are no witness for the first creation .
i will try to check and understand anatomy and physiology
Try reading the Qur'an, honestly, and then you will recognise just how very "limited" your scripture is about the knowledge of human biology.
The lack of details in the Qur'an showed the shortcoming of the scripture in matter of science, because it was written by bunch of primitive Arabs who didn't science at all. They had only understand superstitious myth, folklore and fable, when it come to understanding about human body, about earth science, or about astronomy.
When it come science, there is nothing special about the Qur'an, because it give no knowledge of science whatsoever.
The Qur'an is not a science book; it never was one. It is a book of theology, with bit of laws and ethical codes, and different interpretation of the biblical myths.
I recognize the Qur'an for what it is, written or dictated by man, with primitive and very limited understanding of the world around him. If God was truly the author of the Qur'an, then when it come to matter of science, he is the village idiot.
Seriously, only an idiot would think that human can be made directly from clay (3:49, 5:110, 6:2; 15:26, 28, 33; and many other scattered verses). And like the bible (Genesis 1), the Qur'an (11:7 & 21:30) clearly state the universe or just the earth itself (with the sun, moon, stars in the sky) was made in 6 days. None of these are "scientific", but they are primitive "mythological".
Nature required no planning, no designing by a mythological intelligent being, which you call "god", "creator", or "Allah".
If you truly want to understand the human body, you would seek it out from science, and not some holy books. The Qur'an is a book for only the naive, ignorants and superstitious fools.
