Why are no rocks found that data from the first 800 million years of Earth's existence?
The lack of rocks from the first 800 million years is primarily due to geological processes like erosion, subduction, and intense volcanic activity that have altered or destroyed the original rocks. The Earth's early crust was also likely more unstable and subject to repeated melting and reformation, further contributing to the lack of preserved rocks.
Name two geologic eras that occurred before the existence of the first man?
The Paleozoic Era (541 to 251 million years ago) and the Mesozoic Era (251 to 66 million years ago) occurred before the existence of the first man. These eras were characterized by the emergence and dominance of various life forms, including dinosaurs and early mammals.
Why are no rocks found that date from the first 800 million years of earths existence?
Rocks from the first 800 million years of Earth's existence likely have not survived due to intense geological activity such as volcanic activity, tectonic plate movements, and weathering processes. The Earth's crust during this time was likely unstable and constantly being recycled, making preservation of rocks difficult. Additionally, any rocks that did form may have been subsequently altered or destroyed by subsequent geological processes.
WHO die first on Earth?
It is difficult to pinpoint who was the first person to die on Earth as death has been a natural part of life since the beginning of human existence. Evolutionary evidence suggests that death has been occurring for billions of years across various species on Earth.
When did abundant fossil evidence appear in the geologic record?
Abundant fossil evidence first appeared in the geologic record during the Cambrian Period, around 541 million years ago. This period marked the rapid diversification of multicellular organisms, leading to the Cambrian Explosion, which left behind a rich fossil record of early marine life.
When was the first known existence of Hebrews?
Archaeological evidence for the Hebrews goes back 3600 years, to 1600 BCE. Linguistic evidence for the existence of the Hebrew language goes back 12,000 years.
Who was the first astronomer to present irrefutable evidence of the existence of a black hole?
Charles Thomas Bolton

Why are rocks found that from the first 800 million years of earth existence?
Earth was too hot to have solid rocks at that time.

Which particle did j.j. Thomson discover?
The first discovery of a subatomic particle would come in 1897, when J.J. Thompson first discovered evidence for the existence of the electron.
When did man first walks on two legs?
4.2 to 3.9 million years ago (oldest fossil evidence)
When did the first animals come out of the water?
Some evidence, tracks, put this event at about 500 million years ago.
Is there any evidence for the existence of the virgin Mary?
AnswerThere is no evidence outside the gospels for the existence of Mary, mother of Jesus. Even Paul does not mention her in any of his epistles. If Jesus really did exist, he must have had a mother, and Mary was a common name in Judea of the first century BCE. Other than that, it is a matter of faith alone.
On what continent was the earliest fossil evidence of human found?
the first fossil was found 2.6 million years ago and was a spearhead
What are the raccoon's ancestors?
Fossil evidence shows that the raccoon family first developed in Europe 25 million years ago.
When did abundant fossil evidence first appear in the geologic record?
Abundant fossil evidence first appeared in the geologic record during the Cambrian Period, around 541 million years ago. This period is known as the "Cambrian Explosion" because it marked a rapid diversification of marine life and the emergence of many major animal groups.
