They are never going to be able to evolve something they dont already have. Like being able to breath out of the water. That is the most important aspect of changing from a fish to a land animal, is it not?
Obviously, you've never heard about lungfish. Actually, while the ability to breathe on land is crucial, it's not enough to make an animal ameanable to land life. The buoyancy of the water makes the animals that live in it much less affected by the pull of the earth's gravity, but on land the affect is unrestricted. The force of gravity would have put a heavy strain on the internal organs of the early amphibian transitional fish. The remedy to this is a ribcage, which braces the internal organs and was present in several transtional fish, including a primitive version in the recently found tiktaalik.

There are some things that are FACT.
that the earth is billions of years old.
that the universe is tens of billions of years old.
that evolution happened.
that the record shows that early life was very primative.
that the makeup of life on the earth has changed over time.
--------------------------------------------------------------------------------
I dont see how any of that can be shown as fact.
The entire fields of geology, biology, and astronomy are consistent with the idea that the earth and universe are many billions of years old. Radiometric dating is one, please do not confuse with carbon-14 dating which is only accurate for specimens of a few thousand years and Extrapolation of universal expansion backwards just to name a couple.
Evolution by natural selection has been observed in the laboratory. A good practical example is antibiotic-resistant bacteria. There's also the genetics which prove relationships. BTW, there's not only nuclear DNA but also, mitochondrial DNA. Why would unrelated species show relatedness in two different pieces of DNA? Protein sequencing is a good one, proteins are made of amino acids and there is a redundancy in the code that RNA uses to make amino acids, so animals can make the same proteins but have different codes. The chances that unrelated animals would have mostly the same amino acid codes is ungodly. Also, some mutations give rise to benign genes that have no selection pressures for or against and they accumulate and the chances of most of those to be shared among unrelated species is essentially zero.
The fossil record is very clear in going chronologically from primitive to advanced. This pattern is among the first ones discovered about the fossil record and has withstood at least 50-100 years of scruitiny longer than evolution has.
The last part is pretty obvious when one looks at the fossil record. invertebrates in the cambrian, fish in the devonian, reptiles in the permian, dinosaurs in the mesozoic, mammals and birds since the begining of the cenozoic which we are in right now.
