Fantasy 101 you mean that is mislabeled.The reasons for the dates are simple and well known. They use the present as the key to the past, and assume that the radioactivity (thus-radioactive decay) we see here also existed in Noah's day. Proof? Prove the same laws/nature existed then, or you have religion. Period.
I guess it is too much for some people to actually think about what they are taught.
That’s not how it work with science.
Radioactive isotopes work, decaying at known rate, eg C14, K40 to Ar40, U238 to Pb206, U235 to Pb207, etc, detected, measured and recorded as observed evidence.
If you really think these don’t work, then you must be the one to provide explanation as to WHY it don’t work, and provide evidence that back up your claims.
But you cannot and have not back up your claim with evidence, so it is you who are making baseless claims (claims with no evidence).
So what do you do? You have been trying to burdens of proof upon others.
All you can offered is your personal opinion and made up stories of conspiracy theories of how geologists are working together against Creationism and Intelligent Design. All of this do, is exposed your own ignorance and shine spotlight of lack of honesty and integrity.
The science behind geology, stratigraphy, paleontology, anthropology and biology, isn’t about theism vs atheism, dad. If you look around, a number of arguing against you, are theists, some are Christians, some are Jews and some are Hindus, and some are Baha’i, all of them theism. So it isn’t just atheists or agnostics disagreeing with you.
The differences between you (and other creationists) and them (theists who do have experiences with science), is they understand and accepted science and the evidence that back up the science, is you (like every others creationists) don’t even have the qualification to understand the basic concepts of scientific evidence.
You don’t understand fact or scientific evidence if it punched you in the nose.
