The continental drift theory was replaced by the theory of plate tectonics.
The Continental Drift theory is a theory because there is no evidence to support it. Alfred Wegener developed the Continental Drift theory in the 1800's.
The scientific theory of continental drift was not immediately accepted by geologists.

A hypothesis requires confirmation to advance to the status of theory.
All you would have to do is refute the existing scientific data, through replicateable scientific experiments which support your theory.
A scientific hypothesis could be described as a reasonable guess. If it checks out, it can be promoted to the status of a scientific theory.
