A number of scientists have talked about the interstellar object 3I/ATLAS (C/2023 A3) since it was found in 2025. This is mostly because Dr. Avi Loeb thinks the object could be an alien probe because of its size, path, and chemical ambiguity. This work looks closely at Loeb's claims and gives a fresh astrogeological reason for them: Another group of scientists found that the lithified clastic fragment known as 3I/ATLAS came from a sedimentary basin on an exoplanet that could once host life. I have utilized a combination of observational data and astrogeological reasoning to argue that its properties, like its size (about seven miles), compact coma, and spectral slope, are similar to those of stratified, diagenetically changed siliciclastic strata (could these layers be that similar to Earth?). It explains the features of 3I/ATLAS in a way that makes sense and goes against the idea that a random alien come to visit in such a way proposed by Dr Loeb. High-resolution spectroscopic, mineralogical, and isotopic studies in the future could certainly confirm the new hypothesis proposed by the author and help us learn more about the geology of exoplanets as a whole.
