You have to create one! It picks profile pics etc which you have already shared.

You can search your name here https://profiles.google.com/

It's not true that you have to create a profile. If you want to use Google+, you have to create a profile. If you just want to use Google apps/search/voice/chat/etc. then no, you don't.

Are the public profiles in Google search results? (I'm assuming they are.)
