    “Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth’s crust. But decisive evidence for this phenomenon has proven elusive”, this passage demonstrates seeking proof of a theory over testing a hypothesis violates scientific method. While “Proving a belief” is not good scientific method, it makes for more increased popular media sales. Let’s examine a disproof as well: Growing Earth Theory holds that there is no subduction, but rather the mid ocean rifts in the crust make more surface all the time – but without cycling old material.
