Depends. We can say with scientific certainty that the Bible is wrong on countless fronts. This goes a long way to showing logically that their God doesn't exist.This is such a useless argument. No one can prove God exists, and no one can prove God doesn't exist. Why bother trying.
"God" as a subject is touchy. However it is absolutely no coincidence that the less ridiculous notions and ideas of God (more vague, less personal ideologies of a creator) become, the more they absolutely tend to pull away from any religious ideology.
