There is a large difference between a religious claim and a scientific one. Religious claims are founded and substantiated on purely subjective and unreliable conclusions, while scientific claims are supported by objective evidences. In this essay, I dispel two commonly believed myths that have been proposed by the religious for centuries: that the supernatural exists, and that miracles can occur. I go on to show why everything must have an immutable essence, why the laws of nature are themselves immutable, and why this leads us to conclude that everything is material, that the scope of science is unlimited, and that, while we cannot trust anything a religious person says, we can trust science.
