God created humanity which was already flawed by mortality. The idea that humans were once perfect is a bit of sacrilege - - how could man be perfect without being Gods? The phrase "The Fall" was coined by a Greek church father named Methodius of Olympus - - sometime in the 300's CE. Telling a mortal NOT to touch something BEFORE they learn good from evil makes as much sense as giving a machine gun to a 4 year old and then telling him "whatever you do, don't touch the trigger."
