The Dog-Headed People's Discovery
The war in the stars has ended, but the stars are not the only place for war.
On the other side of the galaxy, a planet visited by Human Civilization, is a different world to this place.
This star field is very empty and quiet. In the vast expanse of space, there is an Orange Dwarf Star. It is a K-Type Main Sequence Star with a lifespan that is longer than that of a solar-like Yellow Dwarf Star.
This Orange Dwarf Star system contains only two planets, one of which is Gaseous Planet smaller than Jupiter and does not have Jupiter's rings. Its orbit is so clean that it doesn't even have a single moon.
As the only Rocky Planet in the Star System, it has 0.59 times the mass of Earth, 0.8 times the diameter, an average surface gravity of 0.69g, a rotation period of 20 hours, 57 minutes, and 33.63 seconds, a calm surface temperature of 36 degrees Celsius, and abundant liquid water on its surface. Like the Gaseous Planet, it has no moons, but it experiences tidal forces, originating from the Giant Gas Planet outside it.
Its orbital period is 17.997 years, which is roughly equivalent to 18 Earth years.
Although this planet has no moons, it possesses a beautiful ring system, much like Saturn's, which presents a mesmerizing spectacle under the light of its Orange Dwarf Star.
The atmosphere is primarily composed of Carbon Dioxide, oxygen, ethylene, water vapor, and nitrogen, with trace amounts of other gases harmful to humans. Carbon Dioxide constitutes the majority, reaching a concentration of 86%, followed by oxygen at 12%, with the remainder being other gases. The abundant Carbon Dioxide provides the planet with an excellent insulating layer, resulting in a greenhouse effect of 22.4 degrees Celsius and an atmospheric pressure of 7 atmospheres.
Such an environment is clearly unsuitable for human habitation, yet life exists here.
This Rocky Planet is covered with towering High Mountain, Snow Mountain- capped peaks, countless towering trees, and dense forests. It has vast continents and turbulent oceans.
There are also snow-capped Snow Mountain that are frozen year-round, but the plants and oceans here are different from those on Earth. Earth's plants are mainly green, while here they are mainly purple. Apart from the color difference, the plants here are generally thicker and stronger than those on Earth, which is likely related to the high concentration of Carbon Dioxide.
Although its sky is also blue, its blue is much lighter than that of Earth, and it looks very clear, but it has no ozone layer.
However, recently, the once clear air seems to have been affected by industrial pollution. The air in some areas appears somewhat turbid, and the ocean, which used to reflect the blue sky, has also been polluted to varying degrees by industrial products.
Many species have gone extinct as a result, but the situation is not severe, at least not to the point that Sentient Life on this planet is unaware of it.
The oceans of this planet also experience tides. Tides occur whenever the planet aligns with its Main Sequence Star Orange Dwarf Star and outer Gaseous Planet, creating a celestial conjunction. Clearly, this astronomical phenomenon is infrequent, resulting in a very long tidal cycle for the planet's oceans, approximately 24 Earth years.
The long tidal cycle keeps its oceans mostly calm and tranquil, except when natural phenomena such as storms occur due to temperature differences across the planet.
Overall, it is a peaceful, purple planet.
But this one planet, whether by luck or misfortune, was visited by a civilization from beyond the stars. From some of the stone carvings now displayed in the museum, it can be seen that the visitors were aliens with saucer-shaped spaceships, giant aliens who were over ten meters tall.
This is the view held by the Sentient Life on this planet. They initially believed the artifacts were some kind of ancient inhabitant, but later it was generally accepted that they were extraterrestrials. This view has been present in their textbooks for fifty years. However, some Sentient Life studying ancient history now believe that the artifacts in the museum represent two different civilizations.
"Look, this stone carving is much older than the descriptions in textbooks. Experts in the relevant academic community believe that the disc-shaped object in this stone carving is an even more ancient alien. Our ancestors saw it in their ignorant times and carved it on the stone wall as a totem."
The tall stone statue to your right is clearly from a different era. Archaeologists have used the latest carbon-14 dating technology to determine that it dates back to our Bronze Age. Scientists are still collecting specific evidence. Here, I want to tell you students that our history textbooks may need to be rewritten.
Inside a sturdy concrete building, a Sentient Life with Comical Dog Head is pointing out some strange objects in the exhibition hall and introducing them to a group of Dog-Headed People.
This Dog-Headed People appears to be a tour guide or something similar.
"Look at this, everyone," the Dog-Headed People tour guide pointed to a rusty pistol encased in a glass case in the exhibition hall. "Doesn't it look familiar? If it does, that's right. It's a gun, the one that caused a sensation across the entire continent back then. What I want to tell you is that this pistol isn't a modern creation, but a weapon of a Bronze Age nobleman. It was excavated from the ruins of a Bronze Age Volcano Kingdom."
"For a long time, we believed this was the creation of our ancestors, but there have always been doubts about this conclusion. Now, the latest authoritative conclusion has emerged: it is an extraterrestrial creation. In other words, during the Bronze Age of our civilization, Alien Civilization visited our planet and left their traces."
Listening to the Dog-Headed People's explanation, one of the tourists, a Dog-Headed People about 2.5 meters tall and quite robust, muttered to himself, "The sun sets in the west, the gods return to their places, light descends upon the world, leading our ancestors through the heavenly gates, then vanishes into the sky. Could the legend of the God of Light descending to earth and bestowing Divine Art before disappearing be true? No, no, no, it should be said that the so-called myths and legends are actually descriptions of extraterrestrials by our ancestors. Doesn't that mean that the ancient legends about the God of Light were not myths fabricated by our ancestors, but rather genuine descriptions of extraterrestrials?"
As he spoke to himself, the decorated Dog-Headed People looked up at the tall sculpture and fell into deep thought. He felt that if the so-called God of Light was an alien, then this tall sculpture was likely some kind of armor.
Of course, we can't rule out the possibility that aliens just look like that.
As to the truth, this Dog-Headed People believes that perhaps we can follow the records of mythology to find the so-called Heavenly Gate.
He remembered that there were descriptions of the Heavenly Gate in mythology. It was said to be a spatial gate set up by the God of Light before he left. By passing through the Heavenly Gate, one could leave this world.
"Heavenly Gate? Spatial Gate?" the Dog-Headed People muttered to himself, a bold idea popping into his mind: he was going to go on an adventure.
