Here's why:
* Pangaea is not the first landmass: Pangaea was a supercontinent that existed about 335 to 175 million years ago. Earth's earliest landmasses formed billions of years before that.
* The name Pangaea is relatively recent: The term "Pangaea" was coined in 1912 by Alfred Wegener, a German meteorologist and geophysicist, to describe the supercontinent he theorized existed in Earth's distant past.
* Continental drift is a modern concept: Wegener's idea of continental drift, the movement of Earth's continents, was initially met with skepticism. It wasn't until the 1960s that evidence from plate tectonics confirmed his theories.
So how do we know about Pangaea?
* Geological evidence: Scientists study rock formations, fossils, and other geological evidence that can be traced across continents, indicating they were once connected.
* Paleomagnetic data: Magnetic minerals in rocks record the Earth's magnetic field at the time they formed. This data reveals that continents have moved significantly over time.
* Computer simulations: Scientists use computer modeling to reconstruct past continental configurations based on geological and paleomagnetic evidence.
In summary: The concept of Pangaea emerged through scientific research and evidence, not through historical records or ancient knowledge. We don't know the names or locations of the very first landmasses on Earth, as they were formed billions of years ago.
