Why did farmers invent plow?

Answer 1

The plow is one of the earliest human inventions. Prior to use of the plow, humans had to simply scatter seeds on the ground or laboriously drive each individual seed into the ground; this limited the amount of food the community could grow. The plow allowed humans to break up the soil, increasing the amount of seeds that could be planted and increasing the odds the seeds would germinate and grow into a plant. There have been some arguments put forth for the idea that the plow is actually the basis of our civilization - it let humans start to develop more complex societies because food became less scarce.
