I believe, because, despite what your post claims, there is not overwhelming evidence against my belief. You seem to claim to have evidence that God definitely does not exist. What is that evidence?
Would you accept any of this as evidence?:
- Supposedly historical stories in several religions contradicted by modern science (Egyptologists seeing no evidence of Exodus where it should be; geologists seeing no evidence of a global flood where it should be; biologists seeing evolution when they should be seeing creation; etc.)
- Archaeological evidence of the development of religions from others, for example, ancient Judaism being pretty clearly an offshoot of Canaanite polytheism rather than the other way around like the Bible says
- Comparative religion and sociological studies showing religious stories developing from cultures with irreconcilable contradictions, quite unlike a world where a religious truth exists beyond culture
- Evolutionary psychology's paradigm of humans as storytelling creatures, and since contradictory gods are based around different stories depending on the culture, this is evidence that gods are more likely to be products of this storytelling tendency than humans are to be products of a god
- Every "God of the gaps" argument made historically has failed up until now
