The fossil record
"Evolutionary theory states that the fossil record represents the transformation of animals from simpler lifeforms to more complex ones over millions of years.
The belief is that the rock layers (geology) represent eons of time and that the organisms which have been fossilized in these rocks show their evolutionary development.
Simpler lifeforms should be found in layers below more complex ones. Charles Darwin also stated that with time, missing links between groups will be found.
Animal remains are preserved as fossils only very rarely under special physical and chemical circumstances. Until today instead of finding millions of missing links, we find that they are still missing. Time and time again we find the most ancient representatives of different animal groups to be just as complex as their modern variants, without any evolution between them. There are literally over a thousand of such so-called “living fossils”. Huge fossil beds, and the remains of animals showing rapid burial all point to the Genesis Flood. As Christians the fossil record—the alleged strongest evidence for evolution—is actually one of the easiest things for us to answer."
