Mythological Creatures

When being a living zombie, it would only make sense to believe in other creatures. Or at least believe in the possibility that there are other creatures out there, weather living in the world of the dark, or in a world all your own. The 'trad' biotics have yet to configure up a logical reason of why we are the way we are. So had it ever crossed their minds that us, 'differently' biotic kids may not be the only abnormal things out there?
