To abelcainsbrother ,
I take it you do not consider Noah' Floods as an explanation to the evidences you speak of?
Fossils and coal and oil are, frankly, great evidence for an extremely ancient Earth, and an extremely long history of life on Earth as well.
What of man creating oil from organic matter in minuets, using pressure heat and water?
What of soft tissue found in dinosaur fossils?
What of diamonds being created in the lab under conditions believed to be happening in the earth, but only taking months to grow?
...just to name a few...
How exactly do the above support a long age earth?
As for dating methods....
I am not an expert but from what I understand, radioactive decay involves obtaining the known half-life of an unstable radioactive element. Often transmutation occurs with the exchange of energy and atoms… effectively a chemical reaction.
Despite known problems and assumptions with dating methods, test are usually performed to confirm suspected dates. When dates match predictions, methods are heralded as accurate and reliable. When they don’t fit the assumed age then contamination and other factors are said to come into play.
A problem exists when the assumption is, that half life’s are calculated as constant and yet we are taught that a chemical reaction cane be slowed or speed up by changing the heat, concentration, pressure affecting surface contact, or the presence of a catalyst.
In a biblical world view we have a global flood, enduring droughts, fire and brimstone from the heavens, changing weather patterns, volcanic eruptions and the dividing of the earth.
In a Scientific world view we see deep time, an ever changing environment, magnetic pole shifts, many ice ages, meteor impacts, vast localized flooding, global volcanic eruptions, mass extinctions.
Both pose problems for accurate reliable dating results.
Many times known ages (eye witness accounts) for recent rock formations have been tested and shown dates grossly over the known age. If known dates cannot be accurately obtained, why should any dates obtained be trusted?
