evolution is not a valid explanation for diverse organisms tracing back to a universal common ancestor.
...
The Bible records the destruction of animals in a global flood with some few being preserved on an ark.
Biological processes have determined that individual animals can speciate and change over time.
Therefore, the animals exiting the ark could account for the diversity we observe today.
Another funny thing about this is that rhutchin tries to use "individual animals can speciate and change over time" [sic] to support "the animals exiting the ark could account for the diversity we observe today". While at the same time denying that "diverse organisms tracing back to a universal common ancestor" is possible. Yet the timescale back to a "universal common ancestor" is
several hundred thousand times as long as the time back to the alleged Ark. (In reality, that is; rhutchin frames his arguments in fantasy).
The issue here is the process that can produce the result. If you start with two animals, such as those coming off the ark, biological processes can lead to the evolution into many species. Start with two canines and you can get all the canines we see today. Start with two felines coming off the ark and you can get all the felines observable today.
If you start with one original organism, there is no biological process that can evolve the animals we observe today no matter how much time is involved.
