Possibly. But, considering that the "Garden of Eden" is a metaphor for the ignorance of the world from which humanity sprung, you wouldn't know the difference if we were still there.
You see, myths about the creation of humanity just aren't true. The Garden of Eden is no more material than the turtles upon which Hindu myth says the world is balanced on.
It might be comfortable for you to think about the world as having been created by an all-knowing, all-seeing "god" that has a definite plan and is keeping an eye on you. Heck, it'd be comfortable for me to think that too. But just because it's a comfortable security blanket doesn't make it real. Even though the alternative: that there is no god, and all of this is made up, and in reality we're just a function of our biological selves; even though this seems a bleak and depressing, that doesn't make it any less "true" than the idea that women were created from man's rib.
Think about it. All your life, you've been taught that there's this warm, peaceful being that has ultimate control over the universe, and probably taught as well that there are certain things that you can do to please this being, and certain things that you can do to anger this being.
Why do you believe that, other than because people generally seem to agree on it?
