The YEC argument is not quite as you put it.
They argue that Jesus refers to the BEGINNING of all things and then states that it was THEN that God made them male and female. The beginning is the same beginning used in Genesis 1:1 and hence it would follow that male and female we both created at the beginning.
Now of course 6 days would be much closer to the “beginning” than billions of years so it would be much more appropriate to say that male and female were created then.
There is no way that one can understand the billions of evolutionary years to mean the same thing.
Of course, once again, as is usual, biologians will have to find a way to negate this since it clearly contradicts the authority of the atheistic religion. Hence the meaning of “the beginning” suddenly takes on some other dimension, not easily understood from a direct reading of the bible. But that does not bother biologians.
Just so by the way - please do take some time to explain how the male and female sex organs developed via the evolutionary pathway? How did such stupendously complex interdepence develop by chance to form the very basis of our human existence on earth?
What’s that? Sorry, I can’t quite hear a clear and scientifically defensible argument, please repeat.
