If you don't care where you will spend eternity, you should know that the only people who will be on the earth for all eternity are those who are in the kingdom of God. Satan has deceived many into thinking that if they allow him to cremate their bodies, while their human spirit is still in them, they will be able to live on the earth for all eternity, and all eternities, and all eternities combined.
What they fail to understand is that many of the people who agree to being cremated, will be cremated while they are still alive and can experience pain. More importantly, if and when they return to the earth, they no longer will have a solar plexus, and will be controlled by Satan's solar plexus. This means that they no longer will be able to engage in independent decision-making.
Most importantly, they cannot remain in the earth during the millennial reign of Christ, and will need to return to their place in hell where they will remain for all eternity, and all eternities, and all eternities combined. They also will never again see the light of day, because hell is as black as the darkest night. There are no stars in hell, no flashlights, no ether lights, and no electric wiring.
The Lord God Almighty El Shaddai
