In the context of Science, seeing (direct or indirect observations with or without instruments) is believing (accepting as truth).
In the Religious context (God, after-life, heaven, hell, angels,…) believing (genuinely and sincerely accepting with the heart) is seeing (accepting a truth).
Most normal human beings function (need to function) in both contexts.
Mixing up the two, often inadvertently, can lead to conflicts and confusions.
