The knowable
Johannes, I think you're on the wrong track when you say
The scientists have proven that space, mass, and energy exist, yet they can not explain how all this came into existence.
It takes "faith" to accept that God (the creator) caused everything to come into existence.
The statement that scientists can't explain how everything came into existence is incorrect; cosmologists are playing with some very interesting theories about that. But the point isn't to belabor that by regaling you with summaries of all the cool cosmology I've been reading recently, but to point out that if you define religion in terms of what science doesn't know, the goalposts will always be moving on you. You need an absolute rather than a relative definition to distinguish the two.
A better differentiation might be based on knowability. Scientists will tell you that the question "Is there a God?" is unknowable by definition, and I think it's more than a way to avoid tedious arguments with endlessly annoying people. "God" is interpreted by a scientist as the joker in the deck who isn't subject to the laws of the universe, therefore can't be described in any intellectually-rigorous way. That defines a conceptually empty area, which is not a very satisfying answer, but at least it isn't a moving target: No matter how much our knowledge grows about the laws of the Universe, there's gonna be that joker God standing just outside the border laughing at us.
(Many cultures have a Creation myth involving a "Joker" or a pantheon including a trickster-deity...they have a piece of the truth too.)
The question of whether something is knowable is kind of like asking "how big is the Universe?". There answer has two faces: The accessible Universe is 12 billion lightyears in radius, but it may actually be larger but it makes no difference because c * age_of_universe = 12gly...anything farther than 12 gly out is inacessible and makes no difference to our universe.
As an analogy for God, that's not bad. The definition is elastic enough to not be broken by any conceivable advance in scientific knowledge. God is always just over the event horizon, so let's get on about our business.
