As part of the project to create a comprehensive employee performance tracking system, a data architect has specified the need for a new table designed to store employee ratings over time. The required schema for this table is as follows: ( employeeId STRING, startDate DATE, avgRating FLOAT ).

Which code block, using a SQL Data Definition Language (DDL) command, would you utilize to create an empty Delta table with the aforementioned schema? The solution should ensure that the table is created even if a table with the same name already exists, without causing errors due to existing table conflicts.
