Where is the circular reasoning? The ratios of isotopes in rocks is measured completely independent of their decay rates. There is nothing circular about it.

CF has always been a site that welcomes people from different backgrounds and beliefs to participate in discussion and even debate. That is the nature of its ministry. In view of recent events emotions are running very high. We need to remind people of some basic principles in debating on this site. We need to be civil when we express differences in opinion. No personal attacks. Avoid you, your statements. Don't characterize an entire political party with comparisons to Fascism or Communism or other extreme movements that committed atrocities. CF is not the place for broad brush or blanket statements about groups and political parties. Put the broad brushes and blankets away when you come to CF, better yet, put them in the incinerator. Debate had no place for them. We need to remember that people that commit acts of violence represent themselves or a small extreme faction.

Everything is circular about it. You start off assuming a same state past and then accredit the very existence of daughter parent ratios and the existence of daughter material TO that unproven same state past.

False. That is the hypothesis that we are testing.
If there was a different state past then using modern decay rates will not produce consistent results from different isotopes for radiometric dating.
If it wasn't a same state past, then using the same state past to determine age using different isotopes with different decay rates would not produce consistent ages.
Not circular at all.

For those who are curious about how these ages are calculated, this page has a decent run through:
http://www.colorado.edu/geolsci/courses/GEOL5690/U-PbNotes.pdf
As you can see, the three different methods (K/Ar, U/Pb Concordia, Rb/Sr isochron) use isotopes with different half lives and very different methods of calculating ages. Even with all of these differences, rocks from the same geologic layer give the same age using these very different and independent measurements.

False. Assigning meaning based on a state you simply believe existed to ratios does not make that state exist! Circular in the absolute extreme.
Yes it would. Ratios that show us more of one type of isotope over another should be consistent. Naturally things were here and doing something in the former state. You just want us to believe for no reason that it was a same state past and that all things only did what they do here. Nonsense.

Yes you can. Nothing to brag about though. I don't even have a defeated wall, let alone any notches in one. Godless religionists who obsess on fanatical evilutionary dreams are what so called science is all about.

From your link..
"This is often a nice example system as you can frequently assume there was no Ar when a rock solidified..."
No. One could only assume that if one blindly assumed a same state past. Gong!
You cannot determine the initial amount of a material based on present state decay!! Get over it. That is religion.

You deny that the underlying assumption and premise for what I quoted from the link was that Ar should be found or not found because of certain physics???

If the same state did not exist then the ages would not agree. Until you address this point, you are barking up the wrong tree.
As one example, the ratio of K/Ar is the same in all meteorites, yet the ratio of Fe/Ni is quite different in all meteorites. This falsifies your claim.
I gave you the reason. The proof of a same state past is the agreement between multiple yet independent radiometric dating methods.

It is easy to prove.
Below is some data from the present in a picture. Wuuldn't you agree it tells us something about the past?
Like "it snowed" and "someone walked through that snow"?

Why would a different state past cause rocks to include Ar at a specific ratio to K that also matched U/Pb (both isotopes) and Rb/Sr in a way that would produce the same age using modern decay rates?
You have yet to answer this question.
The slope of the line in the Rb/Sr isochron gives the age of the rock using that method. Why would a different state past cause an age derived through this method to also agree with the age derived through the completely independent K/Ar method?
I always find it interesting that people who are religious try to discredit an idea by calling it religious.

Your so called ages are 100% ratios, and belief that all we see came from this present state and therefore took a long time to do so. Religion.
It doesn't even address it actually! Who cares about ratios in meteors? Have you some reason they should not be there? You do realize all things were created? Are you suggesting that meteors should somehow have no ratios or isotopes??

If that belief was wrong then ages derived from different isotope pairs would not produce the same age. That is a testable and falsifiable hypothesis. Science.
You claimed that there is consistency in rocks that has nothing to do with a same state past or radioactive decay. I showed that your claim is false. The Fe/Ni ratios are not consistent with the K/Ar ratios. How do you explain this?

Ar is just something that is in creation. Right now it can be produced a certain way. It also reacts a certain way to heat and etc. You are doing nothing in the world but trying to claim that the state was the same in the far past, so that all Ar reacted or came about the same way. Period. If for example Ar would not be destroyed in a molten rock in the former state because of less heat involved and/or different forces behaving in a different way, that govern atomic reactions...then we would not 'reset the clock' in dating! Your whole trip is nothing but blind belief based circular reasoning.
