That's a good point about Eve not being afraid of a
snake--although she was completely innocent at that point---babies aren't afraid of
snakes either, not knowing there is anything to fear about them.
--Joe
I don't think that Eve had any reason to be afraid of a snake back then. Animals were not meat eaters until after the fall, just herbivores.
I get the impression that if Adam named the animals, he didn't do it from afar, but they came up to him. And if they were to be companions of a sort for him, then they must have been tame, in the same way that Isaiah describes animals in the millenium.
