Hi!
So, assuming that you mean a creator as in a religious deity - we're going to run into problems here.
In order for something to be scientifically validated, it has to be proven scientifically by following the scientific method.
As science is based off the physical world, the things we prove must reflect that. The idea of a deity is something which lies <em>outside </em>the physical realm.
This means that any proof that we do find a 'creator', will simply just be something we now know about the physical world.
