Primarily, because it would offend too many religious people if the Matoran didn't worship their God. Anyway, official statements by Greg come down to this:- There is no religion in BIONICLE. None whatsoever. Not with the Matoran, not with the Agori, not with the Great Beings.- What existed on Mata Nui was superstition on the Matoran's behalf, not any firmly established religion, and what happened in the MNOG is deemed semi-canon anyway.Plus, religious discussion, as interesting and philosophically challenging it may be to some, is not desired on BZPower because it sooner or later escalates in flaming and insulting.Which is why Alt. Dimension might want to reconsider his signature. And which is why I am going to close this topic now.
