Did God make man and then the garden...... in Eden...? Was Eden just one land m?

I believe Adam and Eve dwelt in the realm of God which was in The Garden of Eden. I believe God sent them through a portal or star gate that exited on the physical realm of planet Earth. When this happened Adam and Eve could no longer see God and His angels and everything seemed alien to them once they were in the physical realm of Earth. So I now believe that The Garden of Eden was not a physical place on Earth such as a lush park.
