For something like a criminal trial, a scientific (falsifiable) theory, or a matter of logic, I fully agree with what you said.
For something like whether I love a woman, whether blue is my favorite color, or whether there is a God, one has to recognize that these are not scientific questions. It's ridiculous to pretend that they are. The insistence on pretending this is a scientific matter is a rather selfish motivation: to claim a superior position when the truth is, no one has any indication either way in terms of hard evidence.
It's amazing the lengths people will go to in order to tell someone else they're wrong/stupid/etc. This one is cheap because it requires no work and no effort, just a declaration. It's the low-hanging fruit picked by those too dishonest and insecure to admit that in terms of hard evidence, no one really knows.
If you actually are willing to consider it as a real question, there is one thing you may find fascinating. The Golden Ratio keeps popping up everywhere in nature, even when many other values would work. This is not what one would expect from randomness. It particularly pops up in astronomy. I find that most interesting though I would not call it proof.
As for me, I consider the existence of God to be a personal question. I am not arrogant enough to tell you what you should believe, given that same lack of hard evidence. The question itself is not falsifiable and is therefore outside the domain of scientific inquiry. Someone who doesn't understand that is extremely ignorant of the very science they claim to cherish.
