Let’s not get confused between the issue of age of the earth and the issue of Intelligent Design (creation) vs. Darwinism - they are two separate issues.
(Also, let’s not confuse the issue of evolution within an animal group with the issue of Darwinism. There is plenty of evidence of evolution within a major animal group, but of course, that is a separate issue from the Darwinist claim of the origin of the animal group itself. Darwinists love to confuse those two issues.)
The age of the earth which is probably billions or trillions years old, is a separate issue from the intelligent design (ID) of our current living things including man. (True science is a friend of the Bible which suggests man and current living things are about 6000 years old. True science and history has not contradicted that although there have been many fraudulent attempts to do so.)
But “age” is a different issue than “origin”. The Bible says today’s living things including man were intelligently created by an Intelligent Designer - Creator God - while Darwinism claims all living things evolved by themselves from a single organism.
To prove something in science or in law, you need the weight of evidence somewhere between a preponderance (over 50% in favor) up to the weight of evidence being so overwhelming it is proof beyond a reasonable doubt.
Evidence of ID is overwhelming - it is countless and everywhere, beginning with the purposeful makeup one’s own body, its DNA and all the intricate parts that work individually and together that make up a multi-functioning body. Proof of purposeful and intricate design is proof of an Intelligent Designer.
Proof of the requirements of Darwinism which requires 1) a suspension of the second law of thermodynamics and 2) transference between animal groups, is nowhere. True science stands against Darwinism and calls it unscientific and a myth. Darwinism is a lie and one of the great hoaxes of the modern era. As I said earlier, Darwinism is dead they just don’t know it yet.
I’m not confusing one with the other. Evolution needs long ages to maintain even a slight appearance to truth.
The age of anything becomes harder and harder to prove the older the age that is claimed. The scientific method should only rely on predictions, observations and experiments if integrity is to be valued upmost. Predictions, observations and experiments become increasingly impossible and implausible the longer the age ‘assigned’.
‘Assigned’ ages because that is exactly what they are doing, simply circular logic where the dirt defines the age of the fossils and the fossils define the age of the dirt. They want and need long ages therefore that is what they ‘found’ with radio-isotopes even though the radio-isotopes do not agree with each other.
If one trusts the Bible for the life creation account then one must also trust the Bible regarding death and decay - only entered into our world with the original sin - so it completely refutes any idea of long ages. There’s simply no way for life to be dying and transforming life in to new forms when viewed from the Biblical account.
That same Bible also provides ancestry of who begot who and at what ages. Bishop Usher added these up to 4,004 BC while Sir Isaac Newton calculated 3,992 years BC. Adding 2017 years take us slightly beyond 6,000 years, but the keepers of the Talmud tradition have us at 5,778 years since the creation week. Although these ages are not in complete agreement they do indeed all support a very young age for the Earth and Universe.
Micro-evolution [changes within the same kind] is both Biblically and scientifically supported although most avoid the term evolution b/c macro-evolution [change from one kind into another kind] has zero support both Biblically and scientifically. There are no transitional fossils where Darwin claimed there would have to be thousands upon thousands to support his theory.
