They did. Originally the idea was that God wouldn't allow His creations to die out, but later that it violated Uniformitarianism because it was too fast. That idea really held sway until 1981, I believe, when Louis and Walter Alvarez demonstrated that either the K/Pg boundary was a few tens of millions of years long, all over the world, and had the same depositional rate all over the world, or it was a LOT faster than was originally thought.
I guess they thought the Dodo wasn't one of God's creatures.
No problem!
See, dodos were exterminated by humans. God made the beasts for humans to use them as they please. So, if humans used their free will to get rid of them silliy dodos, too bad for the stoopid birds. Same is valid for Tasmanian Tigers and other animals. It's human's rights, brought by God to use nature as we please.
