INTERESTING FACT
Fireflies and Internal Light
Do you wonder where fireflies got their internal light? Fireflies actually contain the so-called Luciferin. This substance when combined with oxygen will enable them to produce light. This process is called bioluminescence and they light up to attract the mate. Same is true with angler fish which also produces light, but they use it to catch the prey.

Energy has to come from somewhere. In the case of fireflies, energy from metabolism is used to produce Luciferin which has high potential energy that is released as light when it is oxidized by oxygen.
For "stupid researches" to produce Luciferin, they would need to expend energy, no doubt much less efficiently than they do now to produce energy.
You would do well not to assume that experts have no idea what they are doing, especially when you obviously have very limited understanding of energy use and thermodynamics.
