And when reading it metaphorically here is another perspective. Adam was the first “finished” product of this long genetic effort. So Eve had to be created from Adam. Eden was in the other dimension. These finished products were chosen to remain in that dimension to enjoy those powers and technology. The serpent was one of the other entity species in that dimension who shared the knowledge that our physical dimension existed. They were cast out from that dimension into our current physical dimension for collaborating with the serpent species.
So there are both good and bad entities and one is protecting us from the others, And from ourselves, and in turn also protecting their own interlaced dimension.
That is certainly feasible. At this point it seems best not to entrench on any dogma.
