Each of my science books said, “This is why we think this; this is how we figured it out; and this is what we still don’t know.” That I can trust. An… - Aron Ra

There are eleven Commandments just in Exodus 20, and that list continues into the next three chapters, with many being ethnospecific and limited to the regional currency of sheep and shekels. It wasn't even relevant then and it has no parallel in the American legal system now, especially since we've freed the slaves, allowed women their own agency, and defied the Commandments by rejecting theocracy, permitting freedom of religion and prohibiting discrimination on the basis of race, creed or national heritage.

I don't believe in marriage, myself. It's an arbitrary human concept with no reality beyond that. It isn't always necessarily romantic; it is often political. Even if you believe in God, and swear to love one another for better or worse, till death do you part, none of that is assured. In fact, evangelicals are statistically more likely to get divorced than people with no religion.

Creationists may refuse to acknowledge geologic time scales, and cannot admit that any new organism might be unable to interbreed with the stock from whence it came because their sacred fables say they were “created each after their own kind”. But of course they can’t say what a “kind’ is either, because it’s impossible to identify any point in taxonomy where everything that ever lived isn’t evidently related to everything else. So they largely ignore phylogenetics altogether. Creationists have to deny macroevolution for the same reason they have to deny transitional species, not because these combined realities can only indicate an animal ancestry, but because either one alone proves that such is at least possible, and creationists are not permitted to admit even that.
