The original Hebrew uses the past definite tense for the verb “finished,” indicating an action completed in the past, never again to occur. The creation was “finished”—once and for all. That is exactly what the First Law of Thermodynamics says. This law (often referred to as the Law of the Conservation of Energy and/or Mass) states that neither matter nor energy can be either created or destroyed.
It was because of this Law that Sir Fred Hoyle’s “Steady-State” (or “Continuous Creation”) Theory was discarded. Hoyle stated that at points in the universe called “irtrons,” matter (or energy) was constantly being created. But, the First Law states just the opposite. Indeed, there is no “creation” ongoing today. It is “finished” exactly as the Bible states.
Genesis 2:1 Thus the heavens and the earth, and all the host of them, were finished.
