At Genesis 1:1, it states: "In the beginning God created the heavens and the earth." By distinguishing the earth separate from "the heavens", our Creator, Jehovah God, is identifying the earth as very special to him, the unique planet in all the universe for life, from the microscopic to the huge, such as the sperm whale, to his final creative act, mankind, to call earth "home".
Thus, in the opening verse of the Bible at Genesis 1:1, God clearly identifies the earth as of vital importance to him, preparing it over the course of 6 "creative" days (in which each "creative" day is several thousand years long) for us as his final act of creation.(Gen 1:26-28) This is like building a beautiful home, making sure everything is just right before moving in.
At Isaiah 45:18, God says: "For this is what Jehovah has said, the Creator of the heavens, He the [true] God, the Former of the earth and the Maker of it, He the One who firmly established it, who did not create it simply for nothing, who formed it even to be inhabited: "I am Jehovah, and there is no one else."
At Isaiah 66, Jehovah says: "The heavens are my throne, and the earth is my footstool."(Isa 66:1) Jesus pointed toward Isaiah 66:1, saying concerning swearing: "However, I say to you: Do not swear at all, neither by heaven, because it is God's throne; nor by earth, because it is the footstool of his feet; nor by Jerusalem, because it is the city of the great King."(Matt 5:34, 35)
Jehovah God purposed for the earth to be home for "meek" or teachable ones forever. David wrote: "But the meek ones themselves will possess the earth, and they will indeed find their exquisite delight in the abundance of peace.....The righteous themselves will possess the earth, and they will reside forever upon it."(Ps 37:11, 29)
