Research almost any culture, as far back as you would like, and most will have worshipped something which they consider a higher power. The sun, wooden idols, statues, planets, you name it. The urge is always there. I am sure that you can obscure the need temporarily if you try hard enough.
Btw, if you have an interest in the subject of man's need to worship, I have heard that Blaise Pascal's collection of spiritual essays, Les Pensées is a good treatment of the subject. Dr. Ravi Zacharias writes contemorary books on the subject as well.
