That is not true. We simply recognize the impossibility of reaching any certain conclusion as to whether there are no god, many gods, some gods, one goddess, demi-gods, etc. Anyone who says they are certain is simply emoting.
I thought you were an atheist. At least they have made some kind of decision.
...based on reason alone.
Scientific empiricism does not guarantee "truth" (whatever that is), but it is the most effective method known for minimizing and discovering errors. Things which have not been scientifically verified may happen to be correct, but the *level* and *type* of certainty are different.
Anyone who says they are certain is simply emoting.
Not necessarily emoting. There are degrees of trust and confidence (say in the expertise of a pilot or a wine-taster) which, while not as justified as scientific rigor, are not due merely to emotion or chance.
