As Sam Harris once remarked, “When religions are right, they are right by accident.” His point highlights the lack of empirical grounding in religious claims, which are typically non-falsifiable and therefore beyond the scope of scientific validation.
Ironically, this may mean that the authors of Genesis were accidentally correct in one of their most iconic assertions: that the universe began with the creation of light (Genesis 1:3). While the biblical writers lacked any scientific understanding, modern physics now suggests that under extreme quantum conditions, something akin to this could indeed occur — light arising from an apparent vacuum.
This is an area where creationists normally tie themselves up in knots, claiming on the one hand that you can't get something out of nothing because it contravenes the laws of thermodynamics and on the other hand that a god made of nothing created the universe out of nothing with some magic words.
The truth, of course, is rather more rational and subject to scientific analysis and testing.
Researchers at the Department of Physics at the University of Oxford have successfully simulated a remarkable prediction of quantum electrodynamics: the spontaneous emergence of photons from empty space. Their work, published in Communications Physics, demonstrates how light can be generated from the quantum vacuum — a phenomenon that, until now, had only existed as a theoretical possibility.
