This depends on one's Biblical perspective.
I am one who believes God's Word points to a previous world when Satan was perfect in his ways following God at His Throne (per the parables in Ezekiel 28 and 31). There is no way that happened during the time of Adam and Eve. The time when God formed Adam from the dust of the ground came later, after Satan had already sinned against God.
Per Revelation 21:4, in the future new heavens and a new earth, we are shown there will be no more death. Even the Revelation 20:14 verse reveals that after Christ's future 1,000 years reign, that death and hell will be cast into the future "lake of fire".
That might be difficult for many to believe, since this present world death seems to be a natural thing. However, with God's perspective, that is a narrow view, because like Rev.21:4 shows, in the world to come there will be no more death.
This also suggests there will be no more sin. Per Romans by Apostle Paul, the wages of sin is death. Apostle John said that the devil sinned from the beginning. That suggests Satan committed the very first sin against God, not Adam and Eve which committed the first sin imparted to the flesh.
Can you wrap your mind around that brethren, a time when there will be no more sin or death?
The question then is, before Satan rebelled, did sin and death not yet exist? I say sin and death did not yet then exist.
