Simple machines were invented by humans, though they are based on principles of physics that can be observed in nature. Early inventors studied natural phenomena and physical forces to create tools like levers, pulleys, and inclined planes. While the concepts behind these machines can be seen in natural occurrences, the specific designs and applications were developed by people to solve practical problems.

Simple machines found at home include a lever (like a seesaw), a pulley (used in curtains), and an inclined plane (ramp for loading). Complex machines include a washing machine, which uses a combination of levers and pulleys, a dishwasher that incorporates multiple simple machines, and a microwave, which combines electrical and mechanical components to heat food. Other examples of complex machines are a blender, vacuum cleaner, and refrigerator. Each of these machines utilizes various simple machines to perform specific tasks efficiently.

Simple machines can be found throughout nature in various forms. For example, the lever is evident in the way animals use their limbs to lift objects, while the incline can be seen in natural ramps like hills or the slopes of mountains. Pulleys can be observed in the way vines and branches lift themselves toward sunlight, and the wheel and axle are mimicked by the way certain seeds roll or spin as they fall. These natural occurrences demonstrate the fundamental principles of physics at work in the environment.
Scientifically, there are no literal "machines," in your mouth. There is mechanical and chemical digestion that occurs in your mouth. The enzymes are chemical. The mechanical are your teeth. Hope this helps.

No one invented the peanut. It is a plant, and food. Therefore it is found in nature.
It wasn't invented but it was discovered from nature aka someone found a pineapple tree :)

Machinery has always existed, of course, it has undergone drastic change over time. Even as far back as the Neolithic age, people found ways to invent make-shift machinery with the resources that were available to them. The largest boom in technology in these machines took place with the Industrial Revolution.
Wheel and axle (steering wheel), levers (door handles), inclined plane (screws), and pulleys (fan belts, etc,) are all simple machines that can be found in a minivan.
