"Materialistic Naturalism asserts that matter is the only reality, and that all the laws of the universe are reducible to mechanical laws."
The position of science is called methodological naturalism.
None of this would matter if government schools were abolished, as they should be.
While natural scientists maybe are methodological naturalist, most are on ontological naturalists, which is to say that they are aethiest. Regardless, the discussion of the origin of life is inevitable a religious/philisopical discussion since a scientist can no more observe the the beginning of the universe than can a priest.
Origin science is not operational science. You can't observe something that by it's nature will only happen once.
