religion as an aspect of human nature deriving from the language we use

[Whateverist]

You need language to have religion, a bark just cant convey complex ideas.

Right but I think they mean that having a concept of past and future leads to questions of what came before and what will come after. Still it does seem a stretch to view it as inevitable to ask what came before everyone one we ever knew, or, what will happen to me after I die.
