Some religions proclaim that some or all matter had a beginning at some point in time. Most do not consider time or space to have had a beginning. Many religions deal with infinite rejuvenation - an infinite time domain universe. I'm not aware of any religion, not including those based on the Bible, whose god is said to have this ability. Some may be able to travel in time but not exist outside of time altogether which is a necessary requirement for the God that exists, who must create a time domain.
Some religions have an uncaring or preoccupied god.
The gods of most of the world's religions fail all of the above tests. Some fail a few. Almost all fail at least one. The religions that do not fail the above tests make glaring scientific blunders which rules their god out as well. Thus, the God that exists is not one of the gods of the world's religions.
