Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE department (creation VARCHAR, department_id VARCHAR)
TABLE: CREATE TABLE management (department_id VARCHAR, head_id VARCHAR)
TABLE: CREATE TABLE head (head_id VARCHAR, born_state VARCHAR)

### Question ###
What are the distinct creation years of the departments managed by a secretary born in state 'Alabama'?

### Accurate SQL ###

SELECT DISTINCT T1.creation FROM department AS T1 JOIN management AS T2 ON T1.department_id = T2.department_id JOIN head AS T3 ON T2.head_id = T3.head_id WHERE T3.born_state = 'Alabama'
