Hi, CosmicAtheist! Welcome to the zoo!
It's a multi-part answer, and I've only got a few minutes right now. 1) you are precisely right about "we still have a use for them but not the same use as our ancestors." Humans don't use the appendix for a digestion chamber, but we seem to use it a little as a reservoir of bacteria to repopulate the gut after a diarrhea attack. 2) Humans have a vomeronasal organ in their noses. We don't use them, though: there are no nerves attached to them, and the "accessory olfactory bulb" of the human brain forms and then is resorbed during fetal development. Monkeys keep theirs and use them to sniff out mates. Gorillas and chimps, though, do like we do.
Maybe I can elaborate on this this weekend......

Re: siple expanation?
In most contexts an ancient written document would be taken as excellent evidence.
Indeed. That's why belief in Poseidon is so widespread today, Faith: the Iliad is an ancient document, and excellent evidence for his rulership over watery stuff.
How does the Fall explain tooth buds in baleen whale embryos? They resorb the buds before birth. Was the Original Mommy Whale standing close to the Tree whan Eve ate the fruit?
