The redneck strike again.

You forgot few important things.
1) The evidence show that the more meat we eat and the more we get sick.

That is true, the evidence does show this, but is irrelevant to the question if we evolved to be able to eat meat.

That is a silly statement indeed.
We are able to eat meat and not die as a junkie is able to use drugs and not die.
This does not means that people could be a lot better without meat or drugs.
The fact that our ancestors evolve despite the fact that they were eating meat here and there does not means that they evolve and survive because they eat meat.

2) The evidence show that meat in a cold country is not as bad as in a hot country as in a cold county the saturated fat can be used to fight the cold.

What evidence?

I guess you never been in the hospitals in some pacific island.
They are full of people with diabetes.
Diabetes usually come when people eat rich food and do little or no exercise.
Before the white man introduce beef these people only eat a bit of pork, chicken and some seafood but not everyday.
The everyday diet was cassava, taro, fruit, nuts and vegies.
Today they go mad for beef but especially for corned beef in the tin.
The quantity of meat that they eat is not any more that the quantity that people eat in the cold countries but the fact is that in the cold countries people get less sick that is why i said that saturated fat can be used to fight the cold to a certain extend.

Not only did other early hominids eat meat, as the previous evidence shows, archaeological evidence also shows humans have always eaten meat. For example below is a cave painting of humans hunting!

Here and there when people did not have enough natural food they restored to eat meat or some of them eat meat as they become addicted but the fact that our body is totally different from carnivore or omnivore means that we evolve as frugivores.

Additionally, we have a significantly shorter bowel length than herbivores which allows us to eat both plants and meat.

Rubbish.
We do have shorter bowel length than herbivores but not as short as carnivores or omnivore.

We also cannot synthesize vitamin B12, and while some animals have bacteria in additional stomach compartments to keep bacteria that produce B12, we do not. We require B12 from our diet which can be obtained either by eating meat or by making supplements. Since humans pre-20th century could not make B12 supplements they must have obtained it from meat.

You haven't got the right information about the b12.

Objection 2: Vitamin B12 is only obtained from meat, dairy, and eggs.
B12 isn’t made by animals, it’s made by bacteria. It’s found where things are unclean (and rotting flesh is dirty). This easily explains why historically it’s been easy to get B12, because until recently we didn’t live in a sanitized environment. Pull a carrot out of the ground and don’t wash it properly, and there’s almost certainly some B12 there. Vegans should take a B12 supplement, not because veganism is unnatural, but because the modern diet is too clean to contain reliable natural sources of dirty B12.
Incidentally, our need for B12 is tiny: 3 micograms a day (not milligrams, micrograms). The amount of B12 you need for your entire life is smaller than four grains of rice.

You can't just pick and choose when to apply scientific principles because it undermines the strength of your argument. All you do is make a claim and then completely fail to address any counter argument other than by either appealing to some completely untestable nonsensical "intuitional science", or to attack the people making those arguments by saying they are addicted to meat eating. I think meat eating is morally wrong, unhealthy, and damaging to the environment. It is however something we have evolved to be able to do. BUT whether we evolved to be able to do something is completely irrelevant to whether we should do something or not, and by making idiotic arguments you merely make vegans look crazy and irrational. You merely making it easier for meat eaters to justify their behaviour, and you are therefore causing more animals to be murdered.

Sorry but i have been through this sort of argument before when i was dealing with smokers.
Many non-smokers were telling me that i should take it easy but the fight was not won by these pacifists.
It was won by a small group of people like me who went to court several times until the politicians realized that there was no way that the law could stay as it was.
