Peace Sha,
Firstly, if you yourself are confused, then you mustn’t accuse me of messing around with the subject whilst thinking that I am also confused. This by itself is illogical.
In order to understand what I was implying, I believe you must first try to grasp and eliminate your confusion by understanding, differentiating and pondering upon what is "God-made" and what is "man-made". If you have mastered this simple notion, then I presume you’ve understood your own confusion based upon the "subject".
For example: my ten year old son, who has no idea what Quran is all about, has been growing up in his very own environment as laid out in this life until he departs. He goes through several phases of life, learning and understanding every aspect of it. One day, he lies about something and gets exposed. The next day he steals something from school and gets punished for. In the following days he gets caught up in a fight and either beats or gets beaten up. On the contrary, he also does his assigned homework and gets rewarded. He works hard and gets paid for. He helps a blind man cross the street one day and gets praised for and so on and so forth. Every phase of real life incidents that he encounters, whether good or bad, he learns, understands and ponders upon them and its outcome. As he grows, he experiences zillion other real life syndromes. He also advances in the academics of ABCD’s and 1234’s, weighing in and upholding them in accordance with his best judgment. He senses the ups and downs of life that carries him along. Gradually, he questions himself and everything that surrounds him and his beliefs, the Creator and the Creation. The question is, did he ever need the Quran to justify his real life experiences which has been specially and specifically "red-carpetted" for him and only him, on this earth.
A topic you chose on this forum: "Buddhism has lessons for us". I hope it has helped somewhat in understanding my points and to get rid of your confusion, not mine.
Hope this has helped.
God Bless.
