Chemical or spiritual, it's cool either way. We all start off as a flash of light in the darkness. By the way:

Maybe this bright light is our "essence" or "soul" and from that moment onwards the biological and esoteric share a symbiosis where the final result is a sentient and self aware human being.
I love it when I learn something new, cheers.

Let's read the official report from Northwestern to clear up a couple of things:
Radiant Zinc Fireworks Reveal Quality of Human Egg
There are a couple of things that the many, many news reports didn't mention.
First is that this isn't actually from fertilization. The observation came from eggs having enzymes from sperm being inserted into the egg.
No actual fertilization occurred, no embryo was produced.
This is due to producing embryos for scientific research is illegal.
The second issue is something that every single paper left out, and is pretty important:
These flashes don't occur in normal conception.
As the zinc is released from the egg, it binds to small molecule probes, which emit light in fluorescence microscopy experiments. Thus the rapid zinc release can be followed as a flash of light that appears as a spark.
These molecule probes are inserted into the egg. It's in the paper, which is (of bloody freaking course) behind a paywall.
But if you were to simply take a sperm sample and an egg and combine them under a microscope there'd be no visible flash.
Keep in mind, IVF is new but not so new that actual flashes of light from producing embryos wouldn't be noticed.
