Kicked out because of how he sinned while on the prehistoric earth. Not for sinning while in heaven.
He is allowed access to heaven, but his home is now confined to the lower atmosphere of the earth.
And you He made alive, who were dead in trespasses and sins, in which you once walked
according to the course of this world, according to the prince of the power of the air, the
spirit who now works in the sons of disobedience."
Ephesians 2:1-2
The Greek word (Aer) we see commonly translated "air" speaks of the lower atmosphere around thew planet.
The ancient Greeks used two words for air.
Aer meant the dim lower atmosphere, and aether meant the bright upper atmosphere above the clouds.
