A good-looking resume/curriculum vita is a business card that represents a person's abilities, also a "stepping stone" to get a good job. For job seekers with the same ability level, if you can make a more professional and attractive resume, you will have a greater chance of getting an interview when HR sees your resume. Because the first impression a good resume gives HR is: you are professional, you value this job, and you are willing to spend time and effort on job hunting.
