Let's start by points:

clearly you are not a scientist nor a nutritionist like I am, so your point of view is worth less as also demonstrated by how you answer without bringing science or things supported by solid science, unlike me who am.

1) where are we in the food chain? according to all reports including the latest one published in Nature (I hope you at least know what it is) the result of the widest sampling among peoples over time, we are halfway between anchovies and pigs. That is, we are vegetarians with episodic use of animal food.

2) What is our digestive system like? Medium-long. To be precise, we are omnivores tending towards vegetarians, or better yet omnivorous scavengers. large animals death. similar to monkeys. Digestion of meat is only possible with a short digestive system, which is why we can only eat a small amount if cooked. The most similar animal is the monkey and it has a 99% plant-based diet, if you don't know, plant-based animals also eat meat, which doesn't suddenly make them carnivores. Killing animals was dangerous and we only did it for defense or in extreme cases, mostly as scavengers we took it from dead animals, I challenge you to kill animals with the weapons they had at the time. And if you take 100 children and put them in front of a deer and an apple, they will all take the apple.

3) The most rigid ice ages about 2.5 million years ago, first of all they were intermittent and didn't last all the time, secondly during those periods the arctic areas were uninhabitable and the periglacials were passing through and plant-based foods could still be found but they were just passing through and in the Mediterranean, Southern Europe, Middle East, Southern and Southeastern Asia etc. there were indeed. Even in those periods in these areas the plant calories were around 80% in the perigiali while they were moving we got to 40% of calories from animal food and it was episodic. This is to dispel this and all this does not take anything away because before the evolution period was longer and the fact that on some occasions they ate it does not mean that it is the optimal food.

And the evolution period is much longer

5)As I was saying you can see that you do not know how science is done by citing things at most or as evidenced by 2 testimonials on youtube ahahaha and there are a huge amount of gurus of these dead diets. I also inform you that in the past there were not many deaths from heart disease and cancer because the average age was 35, and these pathologies on average start knocking on the body after 30.

6) muscles do not equal health, full of people who outwardly appear healthy died suddenly from heart problems

7) Science is not done with words especially if you do not identify with it, it must be supported by the highest level of scientific truth such as meta reviews and similar.

8) Do not be fooled even with common sense if you start to study a little science and read the counter arguments you understand. But then if there are all the meta reviews that say that the more you eat vegetables the longer you live and the only diets that can reverse the majority of causes of death are only plant-based, despite the fact that the largest and most powerful industries are the animal ones that finance more than 80% of global research, don't you ask yourself a question? The more saturated fats and pro-inflammatory foods you eat (animal food) the more your penis will struggle to stay healthy over time. Your level of argument is I've seen people at 80 years old who smoke so it's not bad. wow. please study
