Here are the similarities:
1. They are both “historical sciences” as opposed to experimental science. Instead of testing hypotheses by conducting experiments, both use the historical record to confirm their hypotheses.
2. Both have adherents that completely overstate the theory that is not confirmable even by the historic record. Natural Selection and Evolution no more support atheism than they do any other religion. Farting cows have no more impact on global temperatures than aliens in neighboring galaxies.
3. Those “Darwin” athiests: They’re moonbats.
“Natural Selection and Evolution no more support atheism than they do any other religion”
Bingo.
Now try to sell that to the Doctrinaire Atheists and the misguided Biblical literalists who sold out to them.
The Bible is theology. Evolution is science. Nether one by itself necessarily contradicts the other, except in the limited visions of certain groups.
