In the big picture, is faith in God, revelation from God and prayer worth it?
Do you think of how challenging superstition or faith protects many vulnerable people?
If people do good because they are human and not because God prompts them then is it right to risk giving God any credit when they alone own their good?
Some things religion teaches are absurd and incoherent so all the evidence in the world would not be enough. For example, "You need to believe in a good God to take moral values such as honesty and compassion and justice seriously." The absurdity here is that you are expected to create a faith for yourself and in yourself to do that in order to believe morality is real. Compliance shows you don't think morality is convincing in the first place. God belief would be unimportant if it cannot advance morality and it cannot.
While refuting the evidence a religion presents for its "truths" would not necessarily disprove the claims, recognise how heavily religion depends on bad and incomplete evidence.
Do not waste time trying to disprove something when it is enough to show that
the entity is unreliable and harmful. If disproof is there then fine and
good. But if it is too hard to reach then put most of the energy into
something more helpful.
