Scientific Cognitive God, which is proven and testable. Atheisms are meaningless

Nowadays, there is also a so-called Scientific (cognitive) God. Yes to the many gods created and invented by humans ( Aten, Horus, Mithras, Dionysus, Attis, Krishna, Vishnu, Baal, Thor, Wotan, Borvo, Yahweh, Kukulkan, Marduk, Allah, Re, Zeus, Shiva, Dyḗus, Ahura Mazda, Zurvan, Manitou the Great. ... ) beyond and beside. Of course, this is not a mythological creature, nor is it some natural formation (Sun, trees, springs, animals, stones) for which a personified meaning is invented. Rather, it covers neurological and psychological processes. However, this "God" is proven and can be tested. Human physiology is part of our real world. This also raises the question of the meaninglessness of atheism.
