I will add that i do not believe this happened at the time of the Garden of eden as the scripture says
Revelation 12 : KJV
{8} And prevailed not; neither was their place found any more in heaven."
This means that after this event satan and his angels no longer had access to Heaven.. We read in the Book of Job .. Which happened some time after the times of the times of Eden..
Job 1: KJV
6 "¶ Now there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them. {7} And the LORD said unto Satan, Whence comest thou? Then Satan answered the LORD, and said, From going to and fro in the earth, and from walking up and down in it. {8} And the LORD said unto Satan, Hast thou considered my servant Job, that there is none like him in the earth, a perfect and an upright man, one that feareth God, and escheweth evil?"
So satan still could travel to earth and back to heaven during the times of Job..
When satan is cast down to earth we are told he will be filled with anger because he will know his time is short... If satan has been down here since the time of the garden of Eden it cannot be said that his time would short..
Revelation 12: KJV
12 "Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time."
