On earth. Humans were created with fleshly bodies to live on earth forever. Nothing has changed.
Most people will not go to heaven but will be resurrected back to a restored paradise earth just like God intended in the first place. All who survive Armageddon or have died and remain in God's memory will be resurrected back to the paradise earth. Not to heaven.
