If you put it in that context, then it's not that much sillier than stuff like "Owning a pet lobster in Maine is illegal when that lobster is pregnant" kind of laws. (true law btw)
A good place to start is Language of Creation by Mattieu Pageau and Unseen Realm by Michael Heiser. Nothing in the Bible is there by accident. It all has meaning and connects with the rest of what's there. And the "contradictions" are there on purpose, to draw you in. Think of them like Zen koans that are inviting you into contemplation of what is meant, rather than "oh those ancient people must have missed this one".
I'm saying that when a hollywood actor in a film makes fun of christians and says something like "oh go sacrifice a goat like it says in your bible", they are willfully misrepresenting those verses as "cherry-picking your beliefs and conveniently leaving out the goat stuff", when in fact typically they're quoting verses of legal/historical significance, rather than of a dogmatic/theological nature.
This distinction dos not make sense. The laws in the Bible is literally given by God.
I agree about the old testament, but this is only silly when taken out of context. Long before I got into network security I worked in the Maine Lobster industry shoveling bait (which is half-rotten fish mixed with salt, lobsters love it!) into buckets and weighing/storing lobsters at a fisherman's co-op.
An important part of conservation revolves around people putting fertile female lobsters back in the ocean when they are inadvertently caught. Maine puts a lot more effort into conserving them than the surrounding states/countries do (who frequently get caught poaching in Maine waters and keeping lobsters that would be illegal to keep even if they were allowed to fish in Maine.
Yes, this is kinda the point. It's the Chesterton's Fence argument. Before mocking something which appears silly, try to find out the reason it was created in the first place. Maybe there was good reason, maybe that reason still holds, maybe it doesn't.
