Hi, Chemscience. Welcome to EvC!

I disagree that cosmology has “nothing to do with evolution”. Creation of the universe without God MEANS creation of life w/o God. In my hand is THE ORIGIN OF LIFE by the late M. G. Ruten, Prof/Geology, Univ/Utrercht, Netherlands. The preface is by the illustrious evolutionist A. I. Oparin. which covers some of the same ground I did. Page 155 presents:
“The theory of evolution is based on 7 assumptions:
(1) Non living things gave rise to living material, i.e. spontaneous generation occurred.
(2) Spontaneous generation occurred only once
(3) Viruses, bacteria, plants and animals are all interrelated.
(4) Protozoa gave rise to Metazoa
(5) The various invertebrate phyla are interrelated
(6) The invertebrates gave rise to the vertebrates
(7) Within the vertebrates the fish gave rise to etc etc etc
“the first two assumptions, as we have repeatedly seen in this text, are still hypothetical.
Everybody else has concentrated on the first two assumptions, which deal with abiogenesis, and explained how the Theory of Evolution does not hinge on these. I would like to add that none of the other five are assumptions that the Theory of Evolution relies upon, either.
There are two different models of which you need to be aware: (1) Evolution by Natural Selection (“animals change in a heritable fashion over time, in a process regulated by environmental conditions”)---this I will henceforth abbreviate “ToE,” for convenience; and (2) Natural History (“the retelling of how evolution has played out in the past”). If you think about it, these two models are not at all the same. Note that “natural history” is not, itself, a theory, but is simply a field of study that pieces together how evolution happened in the past. Our understanding of natural history can change a thousand times over without once causing a problem for ToE.
For example:
“Assumption” #3 in your citation states, “viruses, bacteria, plants and animals are all interrelated.”
Natural history states that this is true. But, if viruses arose separately from the primordial soup,
evolution would still be happening. So, the ToE does not require assumption #3, nor does it actually assume assumption #3 at all. In fact, that all organisms are related is actually a
conclusion, based on applying the ToE to the data that has been collected.
“Assumption” #4 in your citation states, “Protozoa gave rise to Metazoa.” Again, notice my parenthetical explanation for the ToE model. What part of, “animals change in a heritable fashion over time, in a process regulated by environmental conditions” hinges on the Metazoa arising from the Protozoa? Only current understanding of
natural history posit this. The mechanism proposed by ToE still functions just the same in a scenario where the Metazoa did not evolve from the Protozoa.
I could continue down the list and show how each of the other “assumptions” is neither required nor assumed by ToE, but is only important to the concept of Natural History. So, when you, or any other creationist, argues against evolution, you should learn to distinguish our current understanding of the world’s history from our current understanding of the mechanisms that have been working throughout that history, because the ToE is really only one of those two things, and it isn’t the one that contradicts Genesis.
