Why do so many people believe that aliens will look like humans?

All we have about aliens is imaginary. They are just a modern day superstition. Nobody has ever seen an alien so they can never know what one looks like. Even though common beliefs suggest that all aliens look almost exactly like us, contactees worldwide since the 1950s have strongly argued that our visitors often appear human but with noticeable differences.

Common Beliefs vs. Scientific Hypotheses

Many contactees have been cited as evidence that aliens resemble humans. For instance, Dutch contactee Stefan Denaerde, a high-profile Scania truck importer, describes his visitors as human yet with slight variance. Daniel Fry, another contactee, also described the space person he spoke to with these traits. These accounts often highlight the idea that our visitors must lower their frequency to ours without proper training, supporting a hypothesis that aliens are trying to adapt to our frequencies.

Convergent Evolution and Alien Morphology

Convergent Evolution: Convergent evolution is the process where traits evolve independently on different species due to similar environmental pressures. This concept suggests that identical or similar physical traits might emerge elsewhere in the universe if they provide significant survival advantages.

Environmental Pressures

Energy Efficiency and Mobility: Bipedalism offers vast energy savings for long-distance travel, freeing the hands for tool use and complex tasks. This adaptation to long-distance travel suggests that similar species might evolve on other planets in analogous environments.

Bipedalism and Brain Development

Brain Evolution and Cranial Development: Bipedalism in humans allowed for larger cranial capacity and advanced brain development. Similarly, alien species might develop large, complex brains to achieve higher cognitive functions and technological advancements.

Manipulation and Dexterity

Opposable Thumbs and Tool Use: The development of opposable thumbs in humans facilitated intricate manipulation of objects and tool creation. Aliens might similarly evolve hands and fingers to manipulate objects, leading to parallel evolutionary paths.

Technological Advancement

The ability to manipulate tools and create technology is crucial for complex communication and survival. Aliens with similar physical traits might evolve to use their environment efficiently, leading to advanced technological capabilities.

Environmental Constraints and Adaptations

Gravity and Physiology: Planets with similar gravitational forces to Earth might favor the evolution of bipedal forms. Higher or lower gravity could lead to overwhelmingly similar or distinct but still bipedal forms. For instance, lower gravity could result in taller, slender beings, while higher gravity might lead to shorter, sturdier forms.

Atmospheric Conditions: Planets with atmospheres similar to Earth might have developed similar respiratory and circulatory systems. These systems are essential for oxygen intake and carbon dioxide expulsion, which are fundamental in sustaining life.

Social Structures and Communication

Facial Features and Expression: Complex facial expressions aid in non-verbal communication, fostering social cohesion and cooperation. Aliens might evolve analogous facial structures for similar needs.

Language and Sound Production: Vocal cords and the ability to produce a wide range of sounds are advantageous for complex communication, leading to the evolution of similar speech apparatus in alien species.

Higher-Dimensional Considerations

Dimensional Constraints on Physiology: In higher space-time dimensions, the need for structural integrity and energy efficiency could lead to convergent physical traits across different intelligent species.

Adaptation to Multiple Dimensions: Alongside adaptation to dimensions, core physiological traits could mirror those of humans if such traits provide a balance between stability, mobility, and cognitive function.

Anthropocentric Bias and Projection

Anthropocentric Bias and Projection: Understanding intelligence and advanced life forms through a strictly human lens (anthropocentric bias) can lead to projecting human-like traits onto potential alien species. This bias is prevalent due to the assumption that similar evolutionary solutions might be universal.

Conclusion

The belief that aliens might have similar physical characteristics to humans, despite vast environmental differences, can be explained through a scientific lens. Convergent evolution, the advantages of bipedalism, brain development, environmental constraints, social structures, and higher-dimensional considerations all contribute to this hypothesis. Understanding these factors offers profound insight into the nature of intelligence and physical form in the universe.
