CNAME for main website, to load balancer?

We are wanting to use an AWS provided load balancer for our main website.

The issue we are running into is that it appears to want us to refer to it by CNAME, which seems to cause problems in the DNS, if we choose to have @ CNAME lb.address.

We could just assign the CNAME to ‘www.examplesite.com’, but then I am not sure how we tell traffic coming to ‘examplesite.com’ to go to ‘www.examplesite.com’.

We are currently using GoDaddy for the DNS, but open to using AWS’s ‘Route 53’ if it could help?

Any guidance would be appreciated.
