Reason why the earth was created.
Isaiah 45:18 For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the LORD; and there is none else.
God formed the earth to be inhabited. The most cursory inspection will reveal that the earth is inhabited. Wherever eye may look there creatures creeping along the ground, climbing up trees, burrowing under ground, swimming in the waters, and flying through the air. Extend your search a little further by procuring a microscope and find tiny organisms that cannot be seen with the unaided eye. I imagine that there yet organisms to small to be seen with even the most powerful microscope. Man cannot figure out everything about God and what he has done.
The scriptures teach that God made the earth to be inhabited and it is inhabited without controversy. It is home to man and countless numbers of creatures. Even the desert and polar regions have their inhabitants. God is a great householder and he has provided and sustained an exquisite, suitable, pleasant land for us to dwell in. The earth is a self-sustaining body that continually renews and refreshes itself. It is not to be compared to celestial bodies--that would be like comparing apples and oranges. The earth is a body terrestrial while the sun, moon, and stars are bodies celestial. There is one glory of the terrestrial and another of the celestial (ref. I Cor. 15). Each realm has its own glory but only the earth is suitable for life. It was made to be inhabited. The earth is preeminent amongst the bodies hanging in the firmament. It predates the creation of the sun, moon, and stars and even the firmament itself (see Genesis 1). It is a special body and has no rivals for that position.
God gave the earth to the children of men--
Psalms 115:16 The heaven, even the heavens, are the LORD'S: but the earth hath he given to the children of men.
The earth is our home. It is vast, beautiful, unique, and interesting--notwithstanding man's shipwreck in the area of obedience.
