How many people did God kill in the Bible?

It's impossible to say for sure, but plenty.  How many did God drown in the flood or burn to death in Sodom and Gomorrah?  How many first-born Egyptians did he kill?  There's just no way to count them all.  This list doesn't include those figures, just like an apartment finder probably won't include square-footage for all rooms.  The list was originally created on http://www.rationalresponders.com.  Many thanks to them.
