PLS-00103: Encountered the symbol "CREATE"

I wrote a SQL script as below, while executing it, encountered 'PLS-00103: Encountered the symbol "CREATE"' error.

logging.sql

DROP SEQUENCE pt_debug_sequence;
CREATE SEQUENCE pt_debug_sequence
      START WITH 1

      NOMAXVALUE
      NOCYCLE
      CACHE 10;

DROP TABLE pt_debug_tab;
CREATE TABLE pt_debug_tab (seq INTEGER, text VARCHAR2(300), datetag VARCHAR2(30));

CREATE OR REPLACE
PROCEDURE pt_debug(inStr VARCHAR2) IS
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
    INSERT INTO pt_debug_tab VALUES(pt_debug_sequence.NEXTVAL, inStr, to_char(sysdate, 'MM/DD/YYYY HH24:MI:SS'));
    COMMIT;
END;

    --select to_char(sysdate, 'MM/DD/YYYY HH:MI:SS') into outtime from dual;

=============

The problem is forgetting to add '/' for the first procedure. When we encounter this kind of issue, usually, we miss adding something or the variable is reserved one etc.
