Except, of course, he was not calling God a liar (even though the Bible does record God lying) but rather calling the people that try to sell fiction as fact mistaken. There has never been a world wide flood in the whole time humans have existed.
Not sure where that reaction comes from, but, yeah, any creature that seeks refuge we feel compelled to try to protect.
I think that that compulsion alone validates us as a species. There's a video out there from Alaska. A polar bear approaches a sled dog chained up. Predator zeroing onto prey. But then the dog takes a playful pose and the polar bear responds in kind with playful behavior.
Behavior is complex. Interspecies behavior is complex. The interplay of the two can be marvelous.
