We don't need to be there to know it...science is the window to the past, present, and future. You can't take the Bible literally yet conform to the techniques and values of science. It is a pity that you didn’t keep browsing through our website, as you would have found lots of information about radiometric dating.If you did, you'd know about radiometric dating and how it is used as irrefutable proof that the Earth by itself is approximately four billion years old. Yes, we are well aware that there are different radioactive isotopes and that they can be used via the technique of radiometric dating to date materials from bone fragments to rocks. From the way you are using the word, it does not seem that you understand its meaning.After all, textbooks, media, and museums glibly present ages of millions of years as fact.Yet few people know how radiometric dating works or bother to ask what assumptions drive the conclusions. This figure wasn’t established by radiometric dating of the earth itself. Radiohalos shouldn’t exist, according to conventional wisdom!Part 2 explains how scientists run into problems when they make assumptions about what happened .An hourglass is a helpful analogy to explain how geologists calculate the ages of rocks.
In order to link the evidence to the accused, the scientists make assumptions, and then they build their interpretations on those assumptions.
