"The universe simply exists"
I understand from the truthful religious knowledge that Universe cannot exist on its own but because G-d helps it to exist for the purpose He created it, else, it cannot exist. And science has no ruling on it. Right, please?

Well, I happen to disagree. In fact, I think quite the opposite: the universe *has* to be uncaused because causlaity only makes sense *within* the universe. I don't agree that any deity is required (or even helpful as an explanation).
You fail to address what 'caused' your deity.
