Inferring causation merely from temporal sequence is the post hoc fallacy.
Evidence
Logicians describe one process of reaching an ultimate fact from insufficient basic facts as the false cause or post hoc fallacy. The fallacy consists of reasoning from sequence to consequence, that is, assuming a causal connection between two events merely because one follows the other. For this reason the fallacy is often referred to as that of post hoc ergo propter hoc (after this and therefore in consequence of this), an expression which itself explains the nature of the error. — Ruggero J.
