Thanks everyone!! I just had another neat thing happen. My husband just asked me today to send him a list of biblical contradictions. Since there are SO many, he wants 5 from OT and 5 from new. He's willing to consider leaving Christianity if the evidence is strong enough. And, this is where he wants to start. I'm pretty lucky, eh?!! 
Hmmm, is your husband really open to atheism?
I think you will find out by seeing if he is asking questions in order to understand or simply to debunk you. I am not sure how a person converts or deconverts.
I haven't read the bible. Only the first few pages (less than 10). No doubt there are many, many contradictions. Are you talking about contradictions with itself or contradictions with scientific knowledge?
No doubt, theists have an answer for it all.
Here are a couple that come to mind
Genesis 1:16
"And God made the lesser light to rule the night"
The moon, as we know is not a source of light. It is a baron piece of rock which reflects the sun's light.
Genesis 1:29
"I give you every seed-bearing plant and every fruit-bearing tree on the face of the earth to be yours for food."
We know that there are many plants which berries will make you sick or dead if consumed as food.
Others will probably provide other examples if you want them to, maybe you already know what you are going to present.
Anyway, good luck. Hopefully, even if he doesn't deconvert, at least he will respect you and your position.
