There is plenty we don't know about gravity, but we sort of went off topic.

There is a difference between theory and faith. I'm not sure how to explain it to you, but it bothers me that you can't tell the difference.

There is none.  It bothers me that you can't realize that.

Theory is simply trying to fill in the blanks with what seems to make the most sense to you specifically based on the blanks that need to be filled in your scientific model.  It's why different scientists often have different theories until people decide to all agree on one.

At least not those kind of theories that can't actually be tested.

Maybe the dictionary will help.

Faith - firm belief in something for which there is no proof

Theory - the analysis of a set of facts in their relation to one another
