Good day,
I had a discussion with a co-worker yesterday, with regards to human development which migrated, as these things do, into a discussion about how a scientist can 'know' that something is millions or billions of years old.
As a bit of background, I am a deconverted Christian with a chemical engineering degree. I normally don't engage in these discussions because I am not a trained cosmologist/biologist/palaeontologist/archaeologist, and I don't like overstepping the bounds of my personal knowledge. The only time I would get involved is if thermodynamics comes up, because that is something I do have advanced knowledge of. My co-worker is a YEC-ist who is also a pastor at a church in addition to our shared job.
The premise of his argument was that we don't (or rather, can't) know that something is millions or billions of years old because there is no 'date' on it. He was aware of radiometric dating, but he didn't seem to believe that those were correct - he used the example of knowing the date of a shipwreck by seeing the date on a coin there, as if to imply that something cannot be dated unless it is marked specifically by a human. He also attempted to cast doubt on radiometric dating by bringing up a mammoth that gave two different dates depending on which part of the animal was tested.
The mammoth claim was easy enough to deal with - a quick search brought up that he was apparently referring to a Kent Hovind lecture where Mr. Hovind was misrepresenting a palaeontological paper. The claim about 'how do you know' was more troublesome, as I couldn't find the correct words to sound convincing. To me, it sounds like he was using a 'were you there?' style argument a la Ken Ham, as if a recorded eyewitness account is more reliable than evidence that can be repeatedly tested. I also believe that his shipwreck analogy fails because there is more than one explanation for a coin of a certain age being on that ship.
So then, I'd like to hear more about this argument - what's been said, what can still be said, what we know, what we don't, etc. - from both sides. I don't know if I plan on engaging my co-worker in this sort of discussion again, but I'm still interested in learning what the argument is.
