Was The German Defeat On The Western Front Caused By the Failure Of The Schlieffen Plan?

Germany's defeat on the Western Front was not caused by the failure of the Schlieffen Plan, the plan failed on September 11th 1914 and the war dragged on for another four years until Germany was defeated on November 11th 1918. The failure of the plan led to many causes such as a war of movement had become a war of attrition (a stalemate). There were long-term and short-term reasons for Germany's defeat as a consequence of the Schlieffen plans failure. However, at the time that the Germans had chosen to put this plan into action, it was Moltke who was in charge. Moltke was not fully happy with the Schlieffen plan, and so because of this he made a few adjustments of his own. It is disputed whether the changes that Moltke made were for the better or for the worse, but despite these changes I feel that the plan still would have failed because there were many underestimations, not least the Russian and Belgium forces.
