Don't a lot of scientist critisize (sp?) religious types when they use this type of logic to prove the existance of God?
"There's no tangible proof, but we can see God's effects so there must be a God."
"There's no tangible proof, but we can see dark matter's effects, so there must be dark matter."
If this type of logic is unacceptable to imply the existance of God, why should it be acceptable to imply the existance of anything else?
