One of the best available arguments against the existence of advanced indigenous or extraterrestrial civilizations on Earth in the distant past is a lack incontrovertibly artificial artifacts or technological byproducts in geological deposits predating modern humans. Even with radioisotope decay, the byproducts of that decay would still be recognizable as such, as with the Oklo natural nuclear reactor. Even in a degraded or decomposed state, if an advanced civilization sent representatives from other stars, or developed on its own from native life forms millions of years ago, detritus from exploration, settling, or accidents might still be found eroding out of badlands, moraines, and other areas of rapid geologic upheaval.
