The Miocene (/ ˈ m aɪ. ə s iː n,-oʊ-/ MY-ə-seen, -oh-) [6] [7] is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words μείων (meíōn, "less") and καινός (kainós, "new") [8] [9] and means "less recent" because it has 18% fewer modern marine invertebrates ...
The Silurian hypothesis is a thought experiment, [1] which assesses modern science's ability to detect evidence of a prior advanced civilization, perhaps several million years ago. The most probable clues for such a civilization could be carbon , radioactive elements or temperature variation.

Earth formed in this manner about 4.54 billion years ago (with an uncertainty of 1%) [25] [26] [4] and was largely completed within 10–20 million years. [27] In June 2023, scientists reported evidence that the planet Earth may have formed in just three million years, much faster than the 10−100 million years thought earlier.
It is estimated that such an asteroid hits Earth about every 500,000 years. [206] 1 million The Geological Society: Within the next 1 million years, Earth will likely have undergone a supervolcanic eruption large enough to erupt 3,200 km 3 of magma, an event comparable to the Toba supereruption 75,000 years ago.

The Eocene (IPA: / ˈ iː ə s iː n, ˈ iː oʊ-/ EE-ə-seen, EE-oh-[5] [6]) is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period in the modern Cenozoic Era.
The Ordovician Period was the geologic period and system that the Earth was in when the rings are believed to have formed. The Ordovician spanned from 486.85 million years ago to 443.1 million years ago. During this period, an event known as the Ordovician meteor event occurred, when a high level of L chondrite meteorites hit Earth. The ...
