Current understanding of the history of life is probably close to the truth because it is based on repeated and careful testing and consideration of data.
The rejection of the validity of fossils and of dating by religious fundamentalists creates a problem for them: Fossil sequences were recognized and established in their broad outlines long before Charles Darwin had even thought of evolution.
Yet fossil/strata dating is crucial to the evolutionary theory!
Without it, the whole thing collapses) (1) None of the other dating methods (the twelve methods discussed in this present chapter) are reliable, but instead are in continual conflict with one another and with fossil/strata dating conclusions. In chapter 17 (Fossils and Strata) we shall discuss in detail the problems associated with fossil and strata dating, but let us right now put to rest a frequently-stated misconception: that radiodating methods have successfully dated and positively established as reliable the dating system conjectures in the so-called "geologic column" of rock strata. ONLY THREE USABLE TEST RESULTS in reality, it is impossible to date sedimentary rock strata and the fossils within it by radioactive mineral dating.
Joachimstal, Bohemia; and (3) 440 million years, the age of the uranium-bearing shale at Gullhogen, Sweden. The Carbon Dioxide released released by burning fossil fuels has too little Carbon-14 because coal, oil and natural gas contain very little Carbon-14 .The Amount of Carbon-14 in today’s atmosphere is not used to as the starting point for Carbon-14 analysis. Atomic testing has doubled the amount of carbon 14 in today’s atmosphere So wood known to be from 1890 is used as the starting point for Carbon14 analysis.Radiocarbon measurements are always reported in terms of years `before present' (BP).This figure is directly based on the proportion of radiocarbon found in the sample.
