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 trip (start_station_id VARCHAR)
TABLE: CREATE TABLE station (lat INTEGER, long INTEGER, id VARCHAR)

### Question ###
What is the average latitude and longitude of the starting points of all trips?

### Accurate SQL ###

SELECT AVG(T1.lat), AVG(T1.long) FROM station AS T1 JOIN trip AS T2 ON T1.id = T2.start_station_id
