I am listening to what you're saying, and I'm not at all attacking vegetarianism, it's a very noble statement.
As I've said, just because someone claims something to be fact, I'm not the type of person to just accept it as fact without questioning if it doesn't make sense to me, it's nothing personal at all.
You said " the fact is we havent developed those things, have we...?
tools, weapons etc werent invented overnight, nor did our superior brains grow overnight, and we spent a lot of time without either, yet we didnt evolve to suit carnivorous needs...and also why werent we simply born with the necessary attributes to be successful hunters - like most other omnivores?" but as was discussed earlier.. you don't have to be a successful hunter to be a carnivore, we were scavengers, I then claimed that maybe we would have adapted physically had we not adapted using tools... which is evolving to suit carnivorous needs, my point was to say that both would lead to the same ending.. humans eating meat.
The reason I asked earlier about other omnivores was because some are built to hunt, as you've said, but seeing as humans hunt in a different way the comparison cannot now be about the hunting side, which is why I was wondering about the internal biology of other omnivores, whether their teeth and digestive system are closer to carnivores or ours because as we're neither carnivores or herbivores, it's other ominivores we should be being compared to.
Carnivores may have the short intestines because they pretty much only eat meat, maybe a meat and vegetable diet would require a long intestine similar to a herbivores because the body requires a longer one to digest vegetables. The presence of a longer intestine doesn't automatically mean we're not built to consume meat, it may simply just mean we're built to consume vegetables as well as meat.
Regarding the teeth, we have incisors but no real meat tearing teeth like other carnivo
