I like the way you said that I have said nothing about evolution, YET. The old age earth and evolution usually go hand in hand, though not necessarily. This is because Neo Darwinian theories require a great amount of time to increase their probabilistic resources.
I think it better to define evolution. Are you speaking of natural selection, which is currently being taught as Neo Darwinism? In this case, the argument is that we breed hundreds of dogs that never existed before. Evolution? Yes. Evolution within a family, not between families. You start out with a dog, and you end up with a dog.
But what is natural selection, and is it a proper vehicle for evolution of species to higher animals? Natural selection occurs within a species, or family, as a natural variability within that gene pool. God designed his creatures to be able to live under highly variable environmental conditions, and so the need for variability within the gene pool. But, as evolutionist have found out, their is limitations to this variability. There is no DNA present to allow for variability outside the family. In order for Neo Darwinism to occur, additional DNA material must be created. This has NEVER happened. EVER. There have never been any transitional fossils found in the fossil record, even though scientists have diligently searched for them for over 150 years. And they have never been able to make it work in the lab.
Lets take another example. The overuse of antibiotics has resulted in many bacteria becoming resistant to current drugs. Some people see this as evolution. Right again, but only within the species. Because of mutations within the bacteria, some bacteria become resistant to certain drugs. But they give up something or pay a price in doing so, because they have decreased the variability of their gene pool. In the absence of the drug, they are actually at a disadvantage. Mutations ALWAYS result in a loss of information, not additional information. This is a serious problem for Darwinist's. You are going the wrong way!! Just like the evolutionary physicists who flaunt the second law of thermodynamics.
One final example. You have probably heard of Francis Crick? He is the one that discovered the language that is found in DNA. A brilliant man, but an atheist and evolutionist. As adamantly as he wanted to coddle his evolutionary theory, Crick finally realized that it is impossible for a language to develop in a random fashion. Anyone with half a brain knows that if you find language, you find an intelligence. So what does he do, abandon his evolutionary ideas and say, you know what, God did it. No, of course not. Instead he comes up with a totally speculative idea with absolutely zero evidence. Directed Panspermia. In other words, aliens dropped off life here. And this is objective science at work. But you know what. The universe is 15.5 billion years old and the earth is only 5.5 billion years, according to evolutionists. There is always hope for evolutionists that if only there is enough time, anything is possible. But according to probability experts, there is not enough time for even a relatively small protein (a basic building block of life) of perhaps 100 amino acids to form spontaneously, even if the earth were a trillion years old.
