I'm not sure if I did a bad job communicating, but there's a disconnect between what I'm trying to say and your response.
A scientific approach apportions beliefs to the evidence. If the scientific conclusion is "we can't definitely say that God does not exist, but we can find no justifiable reason to say he does," it's a rejection of the science to say "oh, but we're going to take the position that God certainly does exist!"
In this regard, many forms of theism - including yours - uses the same tactic as other forms of rejection of science. Pseudoscience and science denialism often comes down to incorrect assessments of certainty: creationist arguments often hinge on under-representing the amount of certainty warranted by the evidence for evolution. People who sell sham medical treatments and products often base their case on over-representing the amount of certainty warranted by poor evidence like anecdotes.
...so in this regard, most theism - including the Baha'i faith - rejects science with regard to gods. "We just don't know" fundamentally conflicts with "we do know... and we're so sure that we're going to build our lives around it."
It all seems straight forward really. If you want to achieve your goal you need the right approach. You use a hammer to bang nails into wood or use a screwdriver for the screws. A drill may make it easier. You could bring out an electron microscope but its the wrong tool!
Medical doctors know that cough mixture is no better than placebo. However the placebo effect is still important. If someone comes to see me and they are convinced the cough mixture the pharmacist gave them is helping them I'm not going to burst their bubble anymore than a homeopathic remedy that I believe to work for exactly the same reason.
I saw a guy who was psychotic once. He was consuming a native plant daily that was known to contain cyanide, under the mistaken impression it would be good for him.

There was good reason to advise if he continued he might die. We had him sectioned under the mental health act until he gained a little more perspective.
To be clear, Baha'is do not take the bible in its entirety literally so would be inclined to reject creationists arguments based on a literal interpretation of genesis in favour of science.
So what is God and how do we measure Him? For Baha'is He is an unknowable essence. That almost sounds like a non-existent essence, doesn't it? So God exists beyond the comprehension of man. No doubt you have heard the Baha'is say the way we come to know God is through His Manifestations. So as we apply a telescope to discern the outer reaches of the galaxy, we use reason and intuition to assess the revelation the God may or may not have produced through His chosen Messenger. For those who sincerely want to find Him, He makes Himself known.
I know that isn't a particularly satisfying answer for you. It seems to me, you don't really want to find God and that's fine. I think you also want to be able to prove to theists such as myself that I have an irrational belief. If so, I can wear it. I'm happy to discuss religion but avoid pushing my beliefs onto others. People come to realisations about God in all sorts of ways, while others decide He doesn't exist, often because His existence makes no sense.
For what its worth, I shared some criteria I would apply in investigating whether or not a prophet of God was who He said He was.
Can we prove or disprove the claims of any Messenger of God?
However there are no established criteria that everyone should use. There's probably some common themes though.
