Scientific knowledge versus spiritual knowledge

[Thumpalumpacus]

Words like evidence, proofs, knowledge, signs, existed way before scientific method.

Atheists want to define words to suit their Agenda. They define "faith" in a way that makes it unreasonable to have.

You asserted a lot.  A child perhaps hasn't proven to itself rationally that it has value, perpetual identity, worth, praise, etc, but it can believe in these things and be justified in doing so.  They can know a moral truth without a long justification of it and express it even the need occurs without requiring to prove it in a long philosophical argument or without relying on the scientific method to prove it.
