have become a subject for investigation by scientists for years. However, de-
spite all the research that has been carried out, humans have not yet pro-
duced a light as prolific as that of fireflies.
It is amazing how a living creature produces light, yet is not adversely af-
fected by its heat. You must have noticed that lamps produce heat as well
as illumination. If you touch a source of light, for example, a light bulb, the
heat burns your hand. So you might wonder how the firefly is not injured
by the heat it produces. In fact, that's what is so amazing about lumines-
cent creatures: the heat they produce does not affect them. That is because
the light produced by these creatures is completely different from what we
use as a medium of illumination. This light is called "cold light", and heat
is not emitted during the production of this type of light. Therefore pro-
duction of this type of light is very effective and scientists have tried for
years to imitate this type of light.
As well as fireflies, various underwater creatures, insects and other species
also produce their own light. Each has a different way to produce its light,
different fields in which to use the light and different durations and types
of light. And each on its own is a wonder.
Obviously, it was not the creatures who equipped themselves with the sys-
tems to produce light and who ensure the continuance of these systems. A
system that produces light in a living creature's body cannot possibly come
into existence as a result of coincidences. Moreover, a structure so perfect
that does not cause any damage to the body could not have possibly
