I would submit that science is different than that. It is an effort to determine how things work (not why, that is the god part) and determine how things work those ideas must be at some level testable, not just by me but by others, and they need to be able to make predictions, and those predictions must work.
One can use faith to say that the world is going to end in some rapture tomorrow, and I suppose if it doesn't one can say I meant Friday, this is not the kind of prediction I am talking about. I'm taking about if I push this rock off of that cliff and it hits that lawn ... how big a hole will it make? And then, I believe the hole is a function of an equation, say f=ma, so can I communicate that equation to somebody in the Czech republic and they use that equation with a different size rock to deliberately create a different hole?
All of the matters on e.g age of the earth, origin of the species, intelligent design or its lack, all of these things influence real predictions I can and do make.
Roll it all the way back to say big-bang stuff? T me it is a matter of the same exercise. A rock, a cliff, and a hole. Now, obviously how to test their's and what to gleen from it is much more challenging, but it is part of the same process to me.
