Were we to discover (or when we do)
that on an exoplanet, there exists a civilization comparable to our own, or
even much farther advanced than us technologically, our initial impulse might
be to declare that, “We are not alone!”
“We,” being humans.
But not so fast. Despite such a discovery, we might yet be
alone after all.
What if, on further investigation, we
discovered that what we had thought to be sentient exo-creatures were instead,
merely beings that had none of the inner thought processes that we have, but
were instead organisms which were only outwardly similar to us, but otherwise
mindless, with no true awareness of the technology they were creating—somewhat
like bees building a beehive, but on a vastly larger and more complex scale?
Although this is extremely unlikely,
the question forces us to ask, what quality truly separates us from other
creatures? What makes us human? Are we
truly apes which took an unlikely turn in the purposeless path of
evolution? Or are we more than that?
Let’s take a look at a few of the most
important features, discoveries or inventions, that might, or might not,
distinguish us from other biological creatures.

Anti-gravity (?)
In each of these categories, there are
those who might quibble over this or that similarity to be found in various
animals—but in humans, these characteristics are far more definitive of us than
they are of any animal.
1. Fire
As far as I know, there is no known
life form apart from humans which can deliberately start and control fires as a
useful tool. This essential ability both
encompasses and enables our technological advance beyond that of, say, the
chimpanzee, or any other creature. (While
a chimp may be taught a rudimentary form of this skill, it is at most only a
pale imitation, and could quickly turn to disaster for the chimpanzee and
others.) There is much more to fire
technology than starting one.
2. Wheel
The pre-Columbian natives of Central
America managed to build very large stone structures without using any wheeled
devices—not even a simple cart. This
demonstrates that the invention of the wheel was not necessarily inevitable,
not even in an advanced society that was skilled in mathematics, astronomy and
architecture—not even when necessity might have been its mother.
Despite this, it is all but
unthinkable that modern technology could have been developed without the
invention of the wheel. Sorry, chimps.
While some purists might dispute the
importance of art as a technology, art is not necessarily always for “art’s own
sake.” It has a dual importance. First, of course, it is expressive of the
human spirit in its many dimensions, from the earliest cave paintings onward. This feature of art should not be
underestimated. Art expresses humanity,
both for better and worse.
But, very importantly, the ability to interpret
the existing world through art, is also connected to the ability to imagine,
design, and innovate new technology.
Many artists would not connect their work to that of the engineering
draftsman, but his drafting skills would likely never have been developed
without the artistic impulse that is unique to humans. And without this skill, especially before
computer assisted design, technology would have remained far less advanced than
otherwise was the case.
4. Writing
Writing is so common today that we
often do not appreciate its truly revolutionary impact. Writing was the first significant, precise
means of mass memory storage external to the brain. It allows communication across not only vast
distances, but across centuries, from generation to generation. No animal apart from humans has ever
developed writing.
5. Agriculture
The ability to grow food and store it,
in quantities to last an entire year, freed human society from the need to hunt
and gather food each day. It became a
safeguard against short periods when wild food was utterly unavailable, during
which time hunger, perhaps starvation, might destroy a clan or tribe. Although there is a kind of ant (leafcutter)
which seems to cultivate fungus for food, this is a far cry from the complex
ability of humans to schedule food production.
Society’s customs and laws are traceable to the social structure imposed
by agriculture.
6. Mathematics
Mathematics gives humanity not only
the ability to count, but also, to measure indirectly, in cases where direct
measurement is impossible. For example,
the Pythagorean theorem allowed men to calculate the distance across a river,
before ever having crossed it. We were
able to calculate the distance to the moon before ever getting there. Mathematics is so foundational to physical
reality that one prominent physicist (Dr. Max Tegmark) has stated that
mathematics does not merely describe the universe, it is the universe.
7. Worship of God
No creature other than humans has a
well-developed sense of the Creator, the Supreme Being, the source and
foundation of all justice, mercy and salvation from sin. While it is fashionable to credit primitive
superstitions with the origin of human worship of God, this is an explanation
more of convenience than demonstrated fact.
Modern philosophy and science have both struggled and failed to explain
why there is something instead of nothing.
They cannot explain how consciousness arises, nor even what it is. Physicalism denies that free will can
possibly exist, which of course would make all human activity a farce, the
acting out of a script that nobody wrote.
In the context of God, life has plan, purpose and meaning.
8. Scientific Method
It is likely that few non-scientists understand
the critical role of the scientific method in modern civilization. Introduced late in human history, it imposed
strict discipline on human thinking.
Until then, brilliant minds had generated strong advances in science and
technology, but they had mistakenly believed that thought and contemplation
alone could unravel the mysteries of the universe. The scientific method is highly
structured. It depends on physical
proof, repeatable by skeptics. Science
is not all encompassing, and its methods do not always work well in, for
example, areas of philosophy and religion, but even so, the scientific method
has revolutionized our ability to comprehend and even predict, physical
phenomena, with amazing detail and accuracy.
9. Relativity and Quantum Theories
These two theories are
counter-intuitive, meaning that they defy ordinary commonsense. Even so, they have proved themselves to be
demonstrably accurate and predictive explanations of physical phenomena. There are of course many other areas of
science which might fit this description, but these two in particular reshaped
scientific thinking in the early years of the twentieth century, and have
prepared the way for many other innovations among scientists. So there, chimpanzees.
10. Electric Motors
Nicola Tesla was the applied scientist’s
equal of pure scientist Albert Einstein.
In a sense, Tesla invented the wheel.
Remember we said that the invention of the wheel was not inevitable. This is also true of Tesla’s electric
motor. Tesla’s motor is at the heart of
modern technology, and had it not yet been invented, we would probably still be
struggling to implement a practical electronic technology.
11. Space Travel
Clearly, no creature on earth, other
than humans, has ever developed the ability to travel to the moon and back, or
to send photo reconnaissance space-ships to Mars, Titan and beyond.
12. Anti-gravity (?)
But wait, you well might say, humanity
has not yet developed a true anti-gravity device, something which harnesses an
as yet undiscovered law of nature, one that allows us to negate the local
effect of gravity, without using the brute force of rocket engines and the
like.
Indeed, we have not done so, and who
knows, may never. I include this final
characteristic in the list for reasons that are partly symbolic, partly
prospective. Humans have the ability,
unique among animals, to imagine doing things that have never been done before,
that defy the limitations of the possible—and then to make them possible.
Are
humans special? If so, in what way?
Characterizing humans as being at the
center of nature, or even above it, has been scorned by many who see us merely
as yet another physical phenomenon of the universe.
Such scorn is often primarily emotional. On the other hand, those who regard humans as
spiritual beings inhabiting a physical body, often fail to make a persuasive
case to skeptics.
It is important for each human to
humbly admit that he cannot answer the eternal questions, and to remain
inquisitive about them. That is a
lifelong endeavor.
