After Adam and Eve were evicted from their Garden they went off into the countryside and continued their evolution practice, without the guidance of Mr. Snake nor a continuing diet of Apples.
They therefore continued their new life direction with no visual means of support nor a job or work contract, so they hunted, fished, picked fruit and pretty much survived for the next mega decades until, along the way some bright spark learned to cultivate the land, grow more and more food as well as raising the odd beast and animals that provided milk as well as more food as well as taking the skin and fluffy coverings to clothe themselves. Mankind was now on the way.
