Here are brief examples for why belief in God is more rational. I'll be glad to discuss in more depth depending on your level of interest in the subject.
- first cause
- best explanation for cause of the Big Bang
- best explanation for fine-tunedness of the universe
- best explanation for the origin of the information in first life forms
- only explanation for natural purpose in things (such as internal organs)
- quantum mechanics suggests the fundamentality of consciousness
- the empirical world is wholly a mental construct, indicating the primacy of information and mind.
- moral realism. This prevailing moral theory is only compatible with theism.
- the applicability of math and logic in a universal, abstract, and invariant framework suggests reality is contained within a universal mind.
- near death, out of body experiences of an afterlife would be considered permissible evidence in court (see "dying declarations").
- the high level of information-richness embedded in reality highly suggests an intelligent source.
