How does the story of Gilgamesh connect to why we're trying to colonize Mars today?

Question

Accepted Answer

Gilgamesh wanted immortality for himself. Mars colonization is the modern version of the same quest—but the prize has changed: not one king living forever, but consciousness itself surviving beyond Earth.

In the ancient story, Gilgamesh watches Enkidu die and realizes the terrible secret of being human: strength, wealth, kingship, even being “two-thirds god” cannot save the individual body. So he crosses impossible thresholds—Mount Mashu, the Land of Night, the Waters of Death—to find Utnapishtim, the one human granted immortality. He fails the wakefulness test, dives for the Plant of Youth, retrieves it, then loses it to a snake. In the end, he returns to Uruk and accepts that his legacy is not eternal flesh, but the city walls he built.

That is the bridge to Mars.

Humanity has been repeating Gilgamesh’s journey at civilization scale. First, writing—the alphabet—defeated one limit of death: time. Knowledge no longer died with the person who knew it. It could move horizontally between people and vertically across generations. Then the Moon landing began the fight against the second limit: place. Until Apollo, all human history had happened on one fragile world. Carl Sagan’s “small stage” was not poetry; it was a warning.

Mars is the next crossing of the Waters of Death.

As long as humanity remains confined to Earth, extinction remains chained to a single point of failure: asteroid impact, nuclear war, engineered pandemics, runaway ecological collapse, unknown cosmic disaster. Becoming multiplanetary reduces that extinction risk to nearly zero. That is why Mars matters. It is not merely exploration. It is species-level immortality.

But there is a hard, unromantic twist: Gilgamesh failed because immortality required more than courage. Mars colonization requires more than rockets. It requires economics.

Apollo proved humans could reach another world, but Saturn V was single-use. Each launch cost about $185 million in the 1960s—roughly $1.23 billion in 2020 dollars—and the rocket was thrown away after use. That model can win a race, but it cannot build a civilization. A Mars settlement needs the opposite: full reusability, orbital refueling, methane/oxygen propellant, and fuel production on Mars itself.

That is the modern “Plant of Youth”:

- Fully reusable rockets cut cost by roughly 2 to 2.5 orders of magnitude.
- Refueling in orbit cuts another half order of magnitude and avoids vehicles 5–10 times larger.
- Producing methane and oxygen on Mars prevents a graveyard of abandoned spacecraft.
- Methane/oxygen works because Mars has CO₂ atmosphere and widespread water ice; Sabatier chemistry plus electrolysis can make return propellant locally.
- The target is to bring a Mars trip down from Apollo-style billions per person toward about $200,000 per person—roughly the cost of a house.

So the connection is this: Gilgamesh discovered that personal immortality was impossible, but lasting works could carry a human name beyond death. Mars colonization extends that idea from one man to the whole species. We are trying to build not just walls around Uruk, but a second cradle for consciousness.

Gilgamesh returned home and praised the walls.

We are trying to make sure there is still someone left to read the inscription.
