Perception
I wonder how early humans would have understood reality if they had a different set of perceptual modalities.
Imagine for a second, there is a species that closely mimics H. sapiens in every way , except its visual system, which allows them to see the cosmic microwave background with their natural sensory organ.
What would their constellation legends be like? Could they have reached the theory of cosmic inflation without going through the helio/geocentric ideas? How would they have theorized the genesis of the cosmos and their place in the universe?
As I mull over what makes humans human, I marvel at the fact humans possess the ability to unearth the laws of nature by artificially furthering the reach of our limited senses. For instance, not only can humans see celestial bodies with our own eyes, but we can also detect the cosmic microwave background - a remnant from an early stage of the universe - with a radio telescope. Furthermore, we can seamlessly augment one scientific conclusion drawn from a set of perceptions (e.g. celestial motion) to another (e.g. differential geometry). Perhaps, that's the quality that makes H. sapiens unique as a sapient species. However, I believe human experience is far more than an aggregate of scientific accomplishments. I sincerely hope The Vault will persuade the readers to ask themselves, 'What Makes Humans Human?'
