If fossils don't prove anything, it sounds like you are rejecting all evidence from the physical world that can be seen, touched and examined. Do the ruins of the Jewish Temple mean anything?
Well, fossils do prove one thing.... the animal lived and died.
They do not say what their great great great grandparents were. They do not say what their great great great grand kids were either. They don't say how many brothers and sisters it had or of it had any offspring of it's own either. Just that this animal lived, and died.
The ruins of the Jewish temple do tell that their was a designer. A designer who designed a building. A designer who had intelligence and purpose for his designs. A designer who proved that the temple:
1/did not come into being by chance
2/ it was created with a purpose
3/ it was destroyed because of that purpose.
A fossil does the same. It proves there was a designer. It was created for a purpose and, now, people purport that it is evidence of chance random appearance of all the animals, in order to destroy the purpose. The purpose God had for each and every kind of animal He created. Evolutionists are trying to take that away from God.
You say that creationists don't deny evolution. From my home, I could walk to churches where ministers preach that only atheists believe in evolution. There is no one creationist position, there are many, a bewildering number. One problem with modern creationists is that what creationists believe today is very different from what literal believers in Genesis believed centuries ago.
Years ago, people believed many different things. As we gain knowledge, these things of belief change.
However, there is still not near the fossil record that was predicted. There is still not any transitional fossils. There is still all the hoaxes and fakes of the past that are still presented as facts.
As time goes on, all we find is how extremely more complex the living cell is. How much more complicated DNA and protein and enzymes are compared to the simple "cell" that Darwin assumed is where life started.
Yet, still, we cannot start life in any way shape or form. Or describe how the first protein was formed, not to mention the complex array and order necessary for any DNA in any tiny one cell, which contains all the information of the entire organism... every cell contains the entire blue print.
No, the more we learn, the less that evolution has left to stand on.
The only reason it stands is due to the fact that it is taught in every school, at every level, every year and if you contradict it...you fail.
It sounds like you are one of those who says that lions, tigers, leopards, cheetahs, pumas and all other cats are descended from Noah's cats. Wolves, foxes, coyotes, dingos, and all members of the dog family are descended from Noah's dogs. That's quite a bit of evolution to happen in a few thousand years.
People who have trouble with this idea of all cats coming from one cat.... forget that cats can have litters at a very young age. So can dogs and rabbits and birds and most other animals...
SO.. this "few thousand years" is not as short as you think. Do you know how many litters of pups that our dog has had in ten years? Do you know how many she would have had in the wild with no control? Or how many females one male will mate with?
We always compare things like this to the life of a human. Humans take way longer. I will have one group of offspring in my 70 or more years.... A dog could have more than 35 times that many.... Kinda shows that the "few thousands of years" could create a myriad of dog types.
And, to top it all off, no matter how many breeds of dogs you create... they are all DOGS.
