You said, no they don't, they prove the theory because they show that we've evolved.

Vestigial organs show that the environmental pressures that a species is subject to have changed over time and that the species has changed because of those changes in environmental pressues. A vestigial organ shows that the species once needed that for some purpose, but no longer needs it. The species has changed physiologically over time due to changes in its environment.
This is consistent with everything evolution teaches. It does not undermine evolution.
Keep in mind that a survival advantage is only important to the evolution of the species if that survival advantage occurs during the reproductive years. If an organ is no longer necessary, as long as it doesn't impair reproductive abilities, it may take quite some time for any changes to occur.
