The lack of scientific evidence supporting the influence of the moon's cycle on human hormonal fluctuations is not due to human narcissism or a lack of interest in studying such phenomena. Scientific research aims to understand and explain natural phenomena based on empirical evidence and rigorous methodologies.

While the moon does have various effects on Earth, such as tidal patterns, its influence on human physiology, particularly hormonal fluctuations, has not been consistently demonstrated in scientific studies. The complexity of human physiology, the multitude of factors that influence hormonal regulation, and the challenges in conducting controlled experiments make it difficult to establish a direct link between the moon's cycle and hormonal changes in humans.

Scientific research continually explores and investigates various aspects of human physiology and the natural world. If there were compelling evidence supporting a significant influence of the moon's cycle on human hormonal fluctuations, it would be an area of active scientific inquiry.

It's important to approach scientific understanding with critical thinking and rely on evidence-based information. If you have any further questions or if there's anything else I can assist you with, please let me know.
