AWS Route 53 not redirecting from www.example.com to example.com

I have a working website at example.com that is stored in my S3. I bought my domain from google so it was a bit of trouble, but I transferred all my MX,CNAME, and other records. Now I have one hosted zone called example.com, inside it are all of these said records, plus amazon's default SOA and NS records. I tried making an A record to my www.example.com and it showed an error since a CNAME value had already taken up that slot. the CNAME's record looked like this: www 3600 IN CNAME ghs.google.com Unfortunately this did not work in terms of directing the www version to the no-prefix version of my website as it gave a DNS error. So I deleted this record and created an Alias with the name www.example.com and then connected it to my S3. (I know my S3 works because I checked the links that S3 provides).

It has been 12 hours and I still see no change in the behavior of looking up www.example.com. I should also note that I was fiddling around and created a new hosted zone for my www.example.com and followed the configuration and even added the 4 pieces of NS to my original DNS provider. I soon deleted them when I figured out this wasn't the correct method.

Please let me know of any suggestions. Thank you.
