Zevi, first off, the first Korbonos offered were given by Kayin and Hevel, which is before any pagan sacrifice. Hashem accepted Hevel’s and tried to encourage Kayin to do better. So I have no idea where you came up with the concept that Korbonos were a consession from Hashem. Please give a reliable source to back up this claim.
Last time I checked donkey’s and horses were not Kosher and yet I don’t see any mention of having more than one pair. They are just as usefull as the kosher animals while the kosher birds, giraffe and goats are not such good use for farmers. So it’s time to rethink that logic or come up with a reliable source to this claim as well. While the Torah does not mention the reason for the 7 clean animals RASHI does and I don’t know about you, his word is good enough for me.
Now that Hashem was pleased “because it was offered to him and not another god” Lets see here, for the past 120 years Noach built a tevia because “Hashem” told him to. “Hashem” warned that he was going to destroy the world. Then “Hashem” brought all of the animals to him and then protected him from assault as the rain started. “Hashem” forced him in and when it was over Noach waited for “Hashem” to give him permission to leave to restart a world that “Hashem” destroyed. Then you want us to think that Noach would in any way shape or form offer a sacrifice to any other diety!?!? So please, enlighten me on your source since this logic is way off for me to comprehend.
I would love to know whom in Lakewood you go to for Da’as Torah since you seem to have a different way of learning Rashi and the meforshim.
By the way I deny the fact that meat is harmful. Our bodies were not ment to be vegetarian since Hashem is the creater of the world and gave us the right to eat meat. Any food that one eats in large quantites is bad for you. I would worry more about refined sugar (and fructose) and white flour which have very bad effects on the body. The key is a balanced diet of whole grains, vegetables, fruit and meat in moderation.
There are many meforshim that say that certain korbonos will still exist after Moshiach as well.
