Genesis 2:4 - These are the generations of the heavens and the earth

2:4

There are some who see the rest of chapter 2 as a second creation account, or even as being in contradiction to the material in chapter 1. Such ideas are simply dumb. Chapters 1 and 2 fit perfectly together. Chapter 1 has looked at the whole of creation, the earth, the stars, all forms of life. As the chapter progressed the focus came ever upon mankind. Chapter 2 now focuses on mankind, as does the rest of the Bible! And the emphasis is on mankind’s relation to God. “These are the generations” is a phrase that occurs several times (e.g. 5:4, 6:9, 10:1 etc) and marks the introduction to a new section.

Genesis is unashamedly geocentric (earth focused). Every so often there are news items about life in other parts of the universe. The simple fact is that we have absolutely no idea whether we are the only inhabited part of the universe, or whether the universe is teeming with life. Scientifically either is possible, the only scientific certainty is that we don’t know. If anyone says there is bound to be life elsewhere in the universe then they are talking nonsense, no matter what qualifications they may have. We do not know what the conditions are for life coming into existence. We do not know how life comes into existence. And we do not know the probability for these unknown conditions to exist. We do not know. Theologically we do not know whether there is life elsewhere in the universe either. Arguments could be made for either possibility.

Note also that it says "generations of the heavens and the earth". Heaven and earth are closely linked!
