When a woman prepares a dish, the only food that will be in there is what she put in there. Of COURSE.
When a building is built, the only materials in the building will be what the builders put in it. OF COURSE.
This holds true for just about everything in life.
EXCEPT - the human being. The male makes his contribution and the woman hers. From that develops a fetus that has EYES, EARS, and MILLIONS of things which were not found in the original material. I mean, where are there SUPER HARD bones in a drop of semen?? Where are there ANKLES AND KNEES???
And the whole thing happens ALL BY ITSELF and after nine months - PRESTO!!!! A LIVING, BREATHING, DROOLING human being!
MA RABU MAASECHA HASHEM!!!! LET US CELBRATE THE MIRACLE OF OUR CREATION!
