    【Question】
    What is the difference in the average age of players when they are drafted in the ABA vs when they are drafted in the NBA between the years 1970 and 1970? ABA refers to lgID = 'ABA'; NBA refers to lgID = 'NBA'; between the years 1970 and 1970 refers to draftYear between 1970 and 1970; difference = subtract(avg(subtract(1970, year(birthDate)) where lgID = 'ABA'), avg(subtract(1970, year(birthDate)) where lgID = 'NBA'))

    【Evidence】
    ABA refers to lgID = 'ABA'; NBA refers to lgID = 'NBA'; between the years 1970 and 1970 refers to draftYear between 1970 and 1970; difference = subtract(avg(subtract(1970, year(birthDate)) where lgID = 'ABA'), avg(subtract(1970, year(birthDate)) where lgID = 'NBA'))

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT CAST(SUM(IIF(T2.lgID = 'ABA', 1970 - strftime('%Y', T3.birthDate), 0)) AS REAL) / COUNT(IIF(T2.lgID = 'ABA', 1, 0)) - CAST(SUM(IIF(T2.lgID = 'NBA', 1970 - strftime('%Y', T3.birthDate), 0)) AS REAL) / COUNT(IIF(T2.lgID = 'NBA', 1, 0)) FROM draft AS T1 INNER JOIN players_teams AS T2 ON T1.tmID = T2.tmID INNER JOIN players AS T3 ON T2.playerID = T3.playerID WHERE T1.draftYear BETWEEN 1970 AND 1970
