One could argue AKA Hume and Kant that all we have are concepts (processed perceptions or thoughts) of the world. The thing in itself (all things including god, especially god) are beyond our ability to know.
So extraterrestrial life is a concept for which we currently have no proof.
If we discover extraterrestial life it remains a concept but one for which we now have objective evidence.
Whether one belieives in god as an actuality, as an existent being, or as just an imaginary friend everyone has some "conception" of the divine or lack thereof. The most powerful concepts (or ideas) in human history and culture are those for which there is not necessarily material proof (freedom, love, justice, truth, and god). To argue about whether they "exist" or if they are "concepts" is to miss the point IMV entirely.
As I pointed out, you and I have the concept (or thought, or idea) of the Eiffel Tower. But that is not the Eiffel Tower. I have been to the Eiffel Tower. It is in Paris. So there are two different entities: the concept of the Eiffel Tower which most of us have, and the Eiffel Tower itself. That seems to me to be clear.
On the other hand, you and I, and many others, have the concept (idea, etc.) of Santa Claus. However, nothing corresponds to this idea of Santa Claus. Which is to say, there ain't no Santa Claus.
Finally, in the Middle Ages, germs existed which caused (as they now do) disease. But, in the Middle Ages, there was no concept of germs. Therefore, there were germs, but no concept of germs.
So, there are concepts, and entities corresponding to those concepts;
There are concepts, but nothing corresponding to those concepts; and, finally entities but no concepts.
The concept, if there is one, is one thing; things or entities, are a different thing. They are independent of each other.
Finally, concepts are themselves things or entities. The concept of Santa Claus is an entity. And, there is a concept of the concept of Santa Claus.
Now. God, if God exists, is not a concept. But the concept of God is a concept. So, to say that the concept of God exists is not to say that God exists.
Notice that atheists, theists, and agnostics, all that the concept of God exists. But atheists and theists disagree on whether God exists. And agnostics do not know whether God exists.
