I don't really care to continue this discussion, because you obviously are quite decided and closed minded on the whole issue.
You ask if other animals are equal to or better than humans? Those are two very subjectively defined words. Certain specific animals are better at certain specific things than us, (this is something that can be empirically tested), and we are better at other things. As I've pointed out, scientifically speaking humans aren't some great exception -- we're just some mutations away from other life on this planet.
I don't know if you figured this out or not, but
1) I am human, so a suggestion that other animals could be superior is the opposite of arrogance.
2) Find the error in your sentence: "back when humans were domesticated..."
Look, half of things you've written don't make any sense. You're what, 18? Also, you have shown considerable ignorance on the information available in regards to animal intelligence and learning. I suggest learning a little humility before forming such big headed and uneducated opinions. I have gone out of my way to spend time with
animals and learn about them. You obviously haven't.
Also, from what I've seen, humans generally base a majority of their decisions on what will gratify them the most with the least work. We are selfish, destructive, greedy, compulsive, and arrogant creatures, and I would not be upset if I were something else, like a killer whale or a wolf.
