Once the first humans left the garden of Eden, where food was plentiful and they just had to gather or hunt they began to farm or raise animals. they gathered the flocks they needed, Sheep , cows, goats, chickens, turkeys and used animals to help them, dogs, birds, horses or camels in their adventures or work. The farmers made spades and what they needed to raise the seeds and other plants they cultivated from the environment. Fishermen made nets and rods and hooks to get the fish they needed or wanted.Humans did then just as they do now but today we have many new tools that have been created by other Humans to help them do the work they need to do.There are many in this world today who still do the same work on small farms as our ancient ancestors did in the past. Land is still cleared by hand, soil is leveled and dug, seeds are planted and watered and it's all still nature it's just not wild anymore. and it's close by the home. Humans don't have to wander far from their gardens or homes.
