If a person claims they are bisexual, for example, how could I or science ever prove that they are or are not? Their behavior might support their claim but it doesn’t necessarily match their identity. Should we just always assume the default/norm (heterosexuality) since we can never prove one way or another? Perhaps god and proof that shows he exists are equally intangible?
Consider another example: A blind woman who was blind from birth trusts me (has faith) when I tell her that what I give her to drink is coffee. A blind people’s lives are completely based on faith- they will never know if what they are smelling is actually coffee or if it is tea (they can be taught to associate scents with something other than what it actually is). Similarly, trying to prove God can be impossible, but it doesn’t mean he doesn’t exist.
