See Leonardo Davinci representing scientists level of ignorance, drawing pre-moulded man, the ‘dwarf embryo’ supposed to grow like a tree in the testis and womb. Beside his picture on the right is Hartsoeker from the 17th century, also depicting the embryo as a pre-moulded miniature man in sperm.
Religion meanwhile 1000s of years earlier had written categorically the facts Science now understands, that man is made not pre-moulded, but as fluid that later gets form, in stages, and the important fact that it is a combination of both fluids from man and woman, and not just man that results in the zygote, embryo and man..

See how 14th century Quran gave them the modern knowledge clearly since long before, had they used Quran earlier(they now do) science would now be 100 steps forward-

Quran
“Woe to man! What has made him reject (Allah)? From what stuff has He created him? From a nutfa (fluid-drop) He has created him, and then moulds him in due proportions.” (80: 17-19).

“then of that fluid-drop (nutfa) We created a leech-like clot” (23:14) .

“then We changed the Alaqa (leech-like clot) into a Mudgha (chewed-like lump) ” (23: 14).

on and on , with accurate modern medical chronological precision…

“then We made out of that mudgha (chewed-like lump of flesh) bones and clothed the bones with flesh; then We developed out of it another creature. So blessed be Allah, the best to create.” (23: 14) .

And see this which conforms precisely with modern medicines categorization of embryological development into three unique characteristic stages-

“He creates you in the wombs of your mothers in stages, one after another, in three veils of darkness.” (39:6),

This below also shows how Moslems believe all this info is not unique to them but is the same info that the earlier prophets had before it got corrupted, and also points to religion categorically stating as fact that man is a combination of both male and female fluids and not just a result of the mans fluids, as science was misguided into thinking till the twentieth century. Listen(read) to this Jew interraction with Prophet Muhammed of Islam-

Imam Ahmed indicated in his book “Al Musnad” that a Jew passed by the Prophet Mohammed (PBUH) while he was addressing his companions. Some people from Quarish said; “O Jew! This man proclaims that he is a prophet.” The Jew said: “ I will ask him of something no one knows except a prophet.” He asked the prophet (PBUH); “ O Mohammed! What is man created from? The Prophet (PBUH) said; “O Jew! Man is created from both: man’s fluid (nutfa) and woman’s fluid.” The Jew said; “This is said by those prophets before you.”
