20 minutes to 30 minutes
So in this segment I see a couple of individuals talking about this idea that there are small volcanoes that erupt today, and that there were bigger volcanoes that erupted in the past (which is undoubtedly true) that deposited greater quantities of lava.
Then there was this conclusion that because events of today, such as volcanic eruptions, might be smaller than some events of the past, that we therefore cannot use events of today to judge this expanse of time of the past.
Personally I think that this is kind of a baseless conclusion.
Was there something different about how volcanoes erupted in the past? No.
And what does that mean with regards to layers that have nothing to do with volcanoes? What is our excuse for them?
What exactly is the real argument here that the individual is making? It's kind of this open-ended thought that doesn't really have a particular technical case to it, it's just more of a broad idea and thought that isn't necessarily justified in anything that he has said.
Moving on...
Then the two individuals talk about radiometric dating and the one says that radiometric dating is where geologists get their idea that the Earth is millions of years old.
But actually this isn't true, scientists have had a number of ways of establishing that the Earth was old long before radiometric dating was ever discovered.
James Hutton was writing about an ancient earth in the 1700s with his observations at siccar point, while radiometric dating really has only been around since perhaps the 1900s? The idea that geologists judge the age of the Earth based on radiometric dating just isn't true. While radiometric dating might be an additional line of evidence for an old earth, it is not the original concept or body of evidence that led geologists to accept that the earth was. It's just icing on the cake, not the cake itself.
Kelvin also had his own estimates in the 1800s as well of an earth hundreds of millions of years old which also predated use of radioactive dating.

Many historical scientists recognized that the earth was ancient long before radioactive dating was ever discovered.

Then the individual talks about collecting samples and sending them to different laboratories for analysis, and receiving results that are different.
What should be said about this is that it's easy to get false data, but how does this individual address situations where multiple laboratories are giving the same result?
Again, it's not a matter of getting different results and debunking a method of analysis, but rather it's a question how you address results when they are yielding the same result? And I'm not talking about numbers one through 10 that happened to be similar, I'm talking about things that are parts per million or parts per billion in precision with each other.
Radiometric Dating Does Work! | National Center for Science Education
Data from independent labs worldwide using various analytical methods for various different isotopes on various samples collected from various locations around the world.
The odds of these laboratories receiving identical results is practically non-existent.
Anyone can go outside with dirt on their hands, pick up a rock and send it into the laboratory and that contamination will yield a false result. And then say "look my result is wrong therefore the method is flawed!". But this just isn't reasonable.
I work with a lot of soil, groundwater and rock dating myself (among other things, air, vapor, surface water, pore water, etc, I do a lot of lab related sampling, or have over the years) and anyone can contaminate samples. Anyone can collect samples that aren't representative of native soil or of a particular rock formation. And this is why we have things like quality assurance and quality control practices. practices where we run blank samples and duplicates and method and equipment blanks and spiked duplicates etc.
So again, it isn't about a bunch of samples giving different results and disproving a method, because anyone can collect bad samples. The question is when quality control and quality assurance is implemented, how do you address scenarios where the analytical results are identical?
The video doesn't talk about any of these quality assurance and quality control practices. And unfortunately these are more of the technical details that the general public doesn't really know about because they don't do the work. So the general public isn't really able to determine if what this individual is saying is true or not because they aren't familiar with the actual work that we do.
This video and the individuals in this video don't talk about any quality control related details, in fact if we were to actually search for this person's research, we would find that their research is in absence of all of these quality control and quality assurance procedures. I know this because I happen to have already looked into this topic, and if anyone is curious about more information, feel free to ask.
Again, it's just an omission of information on the part of those producing the video. Though we shouldnt necessarily expect super high quality information from a YouTube film.
And then they go into discussion about some conspiracy about scientists seeking to take down the Bible because of evolution or something like this.
This final couple minutes of the video segment doesn't involve any technical arguments nor does it address quality control shortcomings of the topics they just discussed nor does it discuss how understanding the age of the Earth was established long before radiometric dating ever existed.
It's more just open claims and people just thinking about philosophical challenges, but they aren't really addressing any technical science, rather they're just kind of openly talking and speaking their thoughts on a topic.
Onward to the next ten minutes!
