Then catastrophic plate tectonics during the Flood stirred the mantle and via partial melting added new rocks to the crust.These new rocks rapidly accumulated more Pb isotopes due to the concurrent accelerated radioactive decay of U and Th in them during the Flood.The HE scheme was first proposed by scientist Cesare Emiliani in 1993.Cesare Emiliani's proposal for a calendar reform sought to solve a number of alleged problems with the current Anno Domini era, which number the years of the commonly accepted world calendar.A useful validity check is that the last single digits of BC and HE equivalent pairs must add up to 1 or 11.
All key dates in human history can then be listed using a simple increasing date scale with smaller dates always occurring before larger dates.
The Holocene calendar, also known as the Holocene Era or Human Era (HE), is a year numbering system that adds exactly 10,000 years to the currently dominant Gregorian calendar (AD or CE) numbering scheme, placing its first year near the beginning of the Holocene geological epoch and the Neolithic Revolution, when humans transitioned from a hunter-gatherer lifestyle to agriculture and fixed settlements.
The current year in the Holocene calendar is 12,018 HE.
These issues include: This is a rough approximation of the start of the current geologic epoch, the Holocene (the name means entirely recent).
The motivation for this is that human civilization (e.g.Nevertheless, the ultimate foundation of this U-Pb dating methodology is the assumption that the earth formed from the solar nebula.
