Metaphysical Solipsism

MetaPhysical Solipsism

Metaphysical solipsism is the "strongest" variety of solipsism. Metaphysical solipist believe that self is the only existing reality and that all other reality, including the external world and other persons, are representations of that self, and have no independent existence.

This would mean that there is no God or higher being which means that all religions are wrong and life is still pointless. There is no after life if you believe in solipsism. If there was only one human left on the planet he would be a solipsist because there is only him.
