Not inability. We're born with the ability to believe in gods. Children believe whatever they're told by a trusted source uncritically, which is why the church is so anxious to get back int the schools and have access to the children of parents who don't teach them about gods or take them to churches.Is it because of your inability to believe in anything that can’t be explained by science?
And not science. Empiricism, or informal science - the "science" we all do every day collecting evidence, generating correct inductions, and confirming and benefitting from them by applying them to specific instances in order to successfully predict outcomes through deduction. That's an acquired skill deliberately and painstakingly cultivated, not an inability to believe by faith. It's an unwillingness.
