the passage is still there to say that the semen determines gender outcome
Sorry but it does NOT read that way to me. You are imposing a biased overlay on top of the way you read that. I have reviewed the passage more than once because I am trying to be a responsible debater, but I still see it as saying that God (or Allah) makes the choice. I can switch viewpoints long enough to say that in that context, I could have once agreed with that statement (that God chooses). But I simply cannot read the statement the way you do.
the number 7 is metaphorical for many.
Using a specific number 7 as a metaphor for "many" speaks ill of the prophet's opinion of the math skills of the people intended to read that passage. Particularly when the word "many" existed at the time the Qur'an was written.
seven heavens and a like number of earths.
If you are going metaphorical on us then that is "many heavens and many earths" but again, why not use the word "many" for this purpose? (NOTE please that I actually do not expect an answer for this one as the Qur'an was written long enough ago that the prophet's reasons for word choices are lost in the deeps of time.)
Also if there were such Qur’anic verses, would you not simply well we have very hot and frozen parts of the planet that we call Earth and that that can’t be proof!
Maybe we would still be skeptical, but that would be harder to discredit because it would have required a deeper knowledge of astronomy than was present at the time. The point of all of this is actually the one you are trying to make... If the Qur'an actually contained some knowledge that COULD NOT POSSIBLY have been known to scholars of that time, then you would have a very good argument. The problem so far is that such extraordinary passages have not been revealed.
People of ancient Egypt knew anatomy of men and women from (if nothing else) preparing bodies for burial using Canopic Jars for the organs. The ancient Chaldeans knew of planets, stars, comets, and other astronomical phenomena. Through animal husbandry including the concept of "breeding mares" and stud animals, they would have been easily able to know about semen.
The passages you have shown us simply don't meet the "extraordinary knowledge" standard. To me, the problem is one of confirmation bias that is causing you to read special meaning into ordinary words. PLEASE believe as you wish, but also understand that when you offer proofs, they are subject to our review and interpretation. I speak only for myself for this: You have EVERY RIGHT to believe as you wish, and must not take it as a personal insult if we don't see things in the same way you do. But you must understand that in the absence of functional telepathy, we CANNOT see things through your eyes, and therein lies the basis of this discussion.
