Atheists routinely put their "faith" in the "unseen" (in the lab). In fact, pretty much anything goes with respect to making claims about the unseen (in the lab), just a long at the topic doesn't involved "God" or "soul".
Normally I would be interested in anything that was established or at least theorised via a robust scientific method which could be checked and replicated by further independent robust scientific method. In discussions with my partner, a practising Christian, she says things like "Don't you look around you and see Gods work in the wonder of the universe" or "How can you explain all this", and my stock answer is normally "I have no idea how the universe started or how life started, it is unknown, I just don't believe it was caused by God" and "I can't explain the origins of all this, but if it was God, where did God come from, who or what made God. The problem is only moved up a level if God is invoked".
Thankfully we don't discuss matters like this very often because there is no winner. God cannot ever be proved scientifically, a belief in God is personal, it is an internally held belief which has no logic. If it could be proved by logic and by science there would only be one god celebrated throughout the world. Similarly science cannot answer all the questions now, and probably will never be able to answer all the questions of life, its origin or the origin and mechanisms of the universe. It seems the deeper we dig into things, the more layers unfold, and maybe it is just all too complex for our puny human brains to work out.
Religious adherents have a lovely fall back position, it was God. Science can only keep digging and peeling away layers, with speculation, theory and observation till a theory meets the observations. That then will suffice until a new observation or a new interpretation comes along and requires the theory to be updated, amended or binned.
In a way I envy the religious adherent for their certainty, they believe if I behave in a certain way and love God/Jesus I WILL get eternal life, it's true because God said so. Whereas we non believers know that if we are wrong we are eternally damned AND worse still, no matter how long we live we will still have so many unanswered questions, which science will be struggling with. It doesn't seem entirely fair.
My partner thinks that one day I might change and "find God" but I've told her that is not going to happen, she thinks it's a shame, but no matter how often I think about it, I just can't "get" God, the whole idea of God seems more unlikely than any scientific theory for the formation of the universe and the arrival of life, that's just my opinion.
