No hedging, no qualification. A flat declaration that time, space and matter had a starting point — and that someone caused it. For most of the twentieth century, that was the one claim science was confident it could refute.

The prevailing consensus held that the universe was eternal and static: it had always existed and always would. A cosmic beginning felt uncomfortably close to religion, and physicists said so openly.

Albert Einstein found that general relativity implied an expanding — and therefore non-eternal — universe. He did not like the implication. He inserted a correction term into his equations, the cosmological constant, to hold the universe still.

The evidence kept arriving anyway.

The evidence piles up

Georges Lemaître, a Belgian priest and physicist, used Einstein’s own equations to argue that the universe was expanding. Edwin Hubble’s observations confirmed that galaxies were moving apart — which, traced backward, points to a single beginning. Then in 1965 Arno Penzias and Robert Wilson stumbled on the cosmic microwave background, the faint afterglow of the Big Bang, and the debate was effectively over.

1. 1917Einstein adds the cosmological constant to keep the universe static.
2. 1927Lemaître derives an expanding universe from relativity itself.
3. 1929Hubble measures the recession of the galaxies.
4. 1965Penzias and Wilson detect the cosmic microwave background.
5. 2003The Borde–Guth–Vilenkin theorem closes the past-eternal exit.

The BGV theorem demonstrated mathematically that any universe expanding on average cannot be past-eternal. It had to have a beginning. Multiverse models do not escape the result; they inherit it.

The Kalam cosmological argument

Philosopher William Lane Craig calls this his most compelling evidence for God. The logic is short enough to hold in one hand.

The structure is valid, and no serious thinker disputes the form. The argument is over the premises.

Premise one asks whether anything has ever simply appeared without a cause. Not in ordinary experience, and not in any verified observation. Quantum fluctuations, which are the usual counter-example, occur inside an existing framework of physical laws and energy. A “nothing” that contains physical laws is not nothing.

Premise two is now the scientific consensus, for the reasons above.

The conclusion follows: the cause of the universe stands outside the universe — beyond time, space and matter. It must be timeless, immaterial and extraordinarily powerful. That is a remarkably precise description of what theologians have always called God.

The numbers are staggering

Roger Penrose calculated the precision required for the universe to begin in the low-entropy state that permits stars, galaxies and life.

The number is not large in any imaginable sense; it is a figure that cannot be written out in a universe this size. Penrose concluded that no natural process explains it.

A nuclear explosion destroys everything in its path. The Big Bang produced a universe of extraordinary order. That asymmetry is what demands an explanation.

Genesis got there first

The Hebrew title of Genesis is Bereshit, literally “in the beginning.” Written millennia ago, it described not merely a creation event but the beginning of time itself. Science spent centuries arriving at what Genesis states in its first word.

The Kalam argument does not prove the God of the Bible specifically. It does dismantle the claim that the universe needs no explanation, and it points to a cause that is timeless, immaterial and incomprehensibly powerful.

That is who Genesis calls God. And Genesis said it first.
