Hi Sienna,

CreatedDate, LastModifiedDate and few others are system fields, mean that fields are populated automatically based on date of record creation or modification (Can not be inserted by user). You can not use them in case of insert or upsert. Please remove those fields from your CSV, created date will automatically populated on your record once the record created.
