Can the close date field on opportunities be left blank during opportunity creation?

Summary:

As it stands now, when an opportunity is created, the close date automatically populates. This makes it so opportunities often times opportunity close dates come and go and the opportunities are still open. If we could leave the close date blank at the time of creation, sales reps would be required to enter a close date that is a better estimation of when the opportunity would actually close.
