It was destroyed and the Earth we now know of today was not inhabited by man.

The other Eden was given to man and when the creation of humanity became perverted and sick it was ended in a great cataclysmic event.

It may be possible by way of God or Gods that a certain number of people were saved and moved to this untainted world, to start over.

The God or Gods, or what may have seemed to be Gods, told a select few what was going to happen and to prepare.

The ones that listened build a ship of immense proportion so that they may make the journey.

Being of God or Gods they knew that man was incapable of understanding the concept of travel to other worlds by other worldly means.

To keep their mind free from the perception of knowledge beyond their comprehension, they had them construct a craft of their understanding to cope with trip to another place.

Shut inside their craft for many days they emerged to find themselves on a new world to start over.

The God or Gods may have transported them to this new world without them even knowing what had happen to them.

It could be achieved by a simple trek across the spaces between worlds, or it could have been a move through the space between spaces; a kind of teleportation.

To extend the notion, a vast many of creatures outside the realm of the travelers sight could have been transported by the God or Gods to the new world even before they themselves had left.

An extension of the mind brings one self face to face with some very hard questions that need answers and you may get them sooner than you think.
