how do I create a wikipedia page about an artist? Will you be able to google the artists name and see there is a wikipedia page?
Topic on Project:Support desk
Google will find the page by itself. Every Wikipedia user can create a new article. Note however, that the person you write about has to be notable! See en:wp:notability for more information!
If the person is not notable according to these guidelines, the article is very likely to be deleted again in the future.
Wikipedia has LOTS of rules about content and most new users will not be able to write an article about an artist that will pass those rules. My advice is to always start by becoming a Wikipedian, and fixing smaller things in many other articles before attempting to write an article on your own.
But besides that. this is the help desk for the software that runs Wikipedia, not for Wikipedia itself. The Help desk for the English Wikipedia can be found here.
