Interstellar immigrant architecture

In fact, the scientific and technological level of underwater city construction in Greece is beyond our reach. In a sense, the level of our human construction is not up to that of Greek cities. So for us, the underwater city in Greece is an unknown building. This does not rule out the remains of ancient humans, but also the remains of highly intelligent creatures. Whether it was built by humans needs further study.

1, probably built by humans.

Sometimes, although scientists call it a non-human building, it is not very scientific. It may also be that the level of ancient architecture far exceeded the cognitive level of modern people, so the level of architecture at that time far exceeded the height of human understanding now, and even in a sense, it may have been built by another highly civilized human group.

2. It may also be the remains of another civilization.

It may be a building left by another intelligent creature from the earth. Moreover, buildings from interstellar immigrants are also very reliable, because many buildings in underwater cities in Greece are not unique buildings on this planet. In a sense, the undersea buildings in Greece may come from higher-dimensional civilizations or may be interstellar immigrants.

3. Architecture of intelligent alien creatures.

The underwater city in Greece may have been built by another high-intelligence organization on another planet. The construction level of human beings is not up to the construction technology of Greek underwater cities. For the whole society, the level and ability of science and technology at that time were completely unreasonable. Therefore, the construction of underwater cities in Greece may come from interstellar civilization and is also a highly developed civilization.

For us, it is still worth considering whether it was built by humans or by an interstellar intelligent creature. Therefore, it may be built by ancient people with high architectural level, or it may be the construction technology from another intelligent biological group. These are not what we can consider and study.
