Religion is far from a universal biological need. The proof of that is in the huge rise of secularity after (i) we began to rationally understand the universe, including deep questions such as how our bodies minds work, the origin the universe, etc, and (ii) religious freedom meant people could freely reject the dominant religion and not be killed for it, which is usually a pretty strong motivator to "love" the dominant religion.
