Why Make Idols?

I am posing this question to everyone who comes across this post. Please do not be afraid to post your thoughts in the comments. All responses are welcome. 

Why do we make idols, especially after God has proven himself to be God? The Israelities were a people who miracle after miracle created idola after idol. Why? 

I am meditating on this question and will post a response whenever I have an answer. 

In the meantime, share with me what is on your mind concerning this!
