Wikipedia:You are not a reliable source

No matter how knowledgeable you may be, you are not a reliable source for Wikipedia content. The reverse is also true, you are not a reliable source for removal of content supported by a reliable source that you think is in error.

There are several reasons why this is so:
 * 1) Readers cannot independently verify your identity.
 * 2) Readers cannot independently verify your credentials. See Reliable sources.
 * 3) Readers cannot independently verify your facts. See Verifiability.
 * 4) Readers cannot independently verify your analysis. See No original research.

What to do if you have a reliable source
If you have a reliable source but don't know how to add a reference, you can put it in your edit summary. Edit summaries have a limit of around 500 characters so you can give more than one source. Better yet, read Help:Referencing for beginners and learn how to add references on your own.
