Ancient peoples collected wild grains to eat as long ago as 20,000 BC, but didn't start growing these crops until 13,000 BC and 6,000 BC, depending on the region.
One of the earliest crops to be domesticated was rice, in China in around 11,000 BC.Agriculture includes animals, of course, and the earliest animals to be domesticated are believed to be pigs, in 13,000 BC in Macedonia. The switch to agriculture is crucial, as it provides a food surplus. This surplus means that not everyone has to be involved in food production, freeing people up to conduct trade and advance science and the arts.Other crucial inventions are the wheel, invented by the Greeks, which allowed people to carry heavy goods; as well as nails, invented by the Romans, without which construction was difficult.Another great, world-shaking invention was the compass. The compass was invented between 200 BC and 100 AD in China. Prior to the compass, mariners had to use the sun and stars to navigate, which meant it was impossible to steer when the sky was overcast. The invention allowed accurate navigation in any weather.

This led to a rise of literacy never seen before and directly contributed to the Protestant Reformation as it allowed average people to access the Bible.One of the greatest inventions, which today we take for granted, is the lightbulb. There were several contributors to the field before Thomas Edison came along, but today he is credited with the invention of the first practical incandescent light bulb. He tried thousands of times to create the light bulb before managing to do so in 1879. This invention revolutionized the world.When asked about the thousands of times he'd failed to create the lightbulb, Edison replied 'I didn't fail. I just found 2,000 ways now not to make a light bulb; I only needed to find one way to make it work.'
