For example, a claim has an ICN of 1114100351480. The third and fourth digits of the ICN are 14, indicating the claim was received in calendar year 2014. The fifth, sixth, and seventh digits of the ICN are 100, indicating the claim was received on the 100th day of the calendar year. As such, the claim was received by Medicare on April 10, 2014.
Until recently, life on Earth was said to have begun 3.5 billion years ago, a date originally based on curvaceous, worm-like strings of microfossils â tiny remains of bacteria, protists, fungi, animals, and plants five-thousandths of a millimetre in length, found in the ancient rocks of Western Australia's Marble Bar.
While it is very possible Earth and other planets were forming 4.56 billion years ago or earlier, we know planet formation for Earth was finished by at least 4.28 billion years ago. This is only one example; there is no known time frame for planet formation, and each planet may have formed at different times and different rates. Planetesimals The planetesimal theory, put forth by Viktor Safronov in 1941, explains planet formation in the early solar system from accretion of small bodies, growing in size as gravity attracted more and more objects.
