This isn't exactly a way of disproving specific things in the Bible, Dragoness, but it's an approach you could take with your husband.
Tell him that you know that there will be no mention of four of the world's seven continents in the Bible. There will be no mention of any of the animals or plants that are particular to any of those four continents. Then tell him that you know this without even reading the Bible cover to cover. Challenge him to find anything in it to show that you're wrong.
The Bible, like all books, is limited to the knowledge of the people writing it, and, if fiction is involved, to the extent of their imaginations.
People in the Middle-East between 2 and 4 thousand years ago had no idea that the continents of North and South America, Australia and Antartica existed, so you can be sure of being right.
So, no racoons, opossums, sloths or kangaroos, but plenty of stuff from the conjoined land masses of Asia, Africa and Europe.
This is not scientific proof against the Bible, merely very strong evidence that it was written by ordinary human beings with, relative to us, very little knowledge of the world they lived in. There is no evidence of the influence of an all seeing, all knowing God being involved in its authorship in any way. Quite the opposite, in fact.
