Zircon is also very resistant to heat and corrosion.
Because of their uranium and thorium content, some zircons undergo metamictization.
In this period a number of comprehensive cosmogonies were proposed.
These were long on armchair speculation and short on substantive supporting evidence.
Though the Samarian and Masoretic texts are much closer, they still have a few differences.
See table 3.8 Using data from table 2 (excluding the Septuagint calculations and including Jones and Ussher), the average date of the creation of the earth is 4045 B. This still yields an average of about 6,000 years for the age of the earth.
If we add up the dates from Adam to Abraham, we get about 2,000 years, using the Masoretic Hebrew text of Genesis 5 and 11.3 Whether Christian or secular, most scholars would agree that Abraham lived about 2,000 B. Quite a few people have done this calculation using the Masoretic text (which is what most English translations are based on) and with careful attention to the biblical details, they have arrived at the same time frame of about 6,000 years, or about 4000 B. Two of the most popular, and perhaps best, are a recent work by Dr. The first four in table 2 (bolded) are calculated from the Septuagint, which gives ages for the patriarchs’ firstborn much higher than the Masoretic text or the Samarian Pentateuch (a version of the Old Testament from the Jews in Samaria just before Christ).
