Why do humans cook meat and food for? Why did it become a world wide trend? Every other creature in the world doesnt "cook"?

It makes the proteins and nutrients more 'available' and allows for a bigger brain. Brains like ours require a lot of energy.

Before the advent of being able to control fire, the hominid diet was limited to mostly plant parts composed of simple sugars and carbohydrates such as seeds, flowers, and fleshy fruits. Parts of the plant such as stems, mature leaves, enlarged roots, and tubers would have been inaccessible as a food source due to the indigestibility of raw cellulose and starch. Cooking, however, made starchy and fibrous foods edible and greatly increased the diversity of other foods available to early humans. Toxin-containing foods including seeds and similar carbohydrate sources, such as cyanogenic glycosides found in linseed and cassava, were incorporated into their diets as cooking rendered them non-toxic.
Cooking could also kill parasites, reduce the amount of energy required for chewing and digestion, and release more nutrients from plants and meat. Due to the difficulty of chewing raw meat and digesting tough proteins (e.g. collagen) and carbohydrates, the development of cooking served as an effective mechanism to efficiently process meat and allow for its consumption in larger quantities. With its high caloric density and store of important nutrients, meat thus became a staple in the diet of early humans. By increasing digestibility, cooking allowed hominids to maximize the energy gained from consuming foods. Studies show that caloric intake from cooking starches improves 12-35% and 45-78% for protein. As a result of the increases in net energy gain from food consumption, survival and reproductive rates in hominids increased. Through lowering food toxicity and increasing nutritive yield, cooking allows for an earlier weaning age, permitting females to have more children. In this way too it facilitates population growth.

Basically, because it TASTES a whole lot better, besides anything else. Do you think that our million-year old ancestors would have bothered going to all that trouble if they didn't actually ENJOY it ? But if it bothers you, just carry on eating everything raw. It's just as good for you.

Our ancestor Homo erectus invented the controlled use of fire and H. erectus first evolved 1.8 million years ago. So, even before we evolved as a species the use of fire have been going on for a long time. Fire can kill germs and parasites, and germs can cause food poisoning. Therefore cooking allows us to avoid food poisoning and reduce parasitism, making us more healthy.. Since other animals do not know how to start a fire they obviously cannot cook their food, even if it is advantageous to do so. Cooking (stewing) can tenderize tough cuts of meat, making them edible. During a time of food shortage, being able to eat what otherwise is not edible or palatable can be a life saver. Cooking can turn powdered grain into bread, pasta and noodles. That gives us more food to eat to avoid starvation. Cooking therefore is beneficial. THe reason other animals do not do it is because they do not know how to start a fire.

Cooking is essentially a form of pre digestion that allows humans to gain more benefit from eating food. The relationship between cooking and human development is quite a popular topic in anthropology.

Many complex reasons, and a chicken and egg argument about cooking driving human evolution viz:
"Heat makes food softer, so less time is needed for chewing. It also releases more calories. Mice fed cooked food get fatter than those fed equivalent raw calories. Heat-treated food is also safer. Scavenged meat has high levels of pathogens. Roasting it on hot coals kills off germs that cause food poisoning. Another benefit of cooking is that it makes otherwise inedible foods, such as tubers, edible. And it frees up time to do more interesting things than just finding food and eating."

Maybe because we would become sick if we did not cook the meat.

In case you haven't noticed humans aren't anything like every other creature in the world. No other species even uses fire to its advantage!
