No, microwave ovens were not invented by Jesus in 1776. The invention of the microwave oven is a product of modern technology and has no historical connection to Jesus or the year 1776.
The development of microwave ovens can be traced back to the mid-20th century. The microwave oven, as we know it today, was invented by Percy Spencer, an engineer at the Raytheon Corporation, in 1945. While working on radar technology during World War II, Spencer noticed that a candy bar in his pocket had melted due to the microwave radiation emitted by a magnetron (a vacuum tube used in radar systems). This observation led to the development of the first microwave oven.
Microwave ovens became commercially available in the late 1940s and early 1950s. They have since undergone significant advancements and have become common household appliances for cooking, heating, and defrosting food quickly using microwave radiation.
