"Faith" in god doesn't exist. All theists believe they have "proof" by repetitive self persuasion resulting, not in faith, but delusion.
If anyone had faith, how come we can come to a site like this and find a never ending stream of obvious lies? I don't need to lie about the big bang or evolution I know what's fact and what's theory and I state it as it is. If theists had faith they would accept the bible and wouldn't need to defend it, they wouldn't feel the need to lie about proofs offered to prove their god false or re-interpret their scriptures to meet the proof offered by science..
Has anyone come out of the jungle and said: "I had an epiphany about god and have faith it exists, do you have any documents?" No. Everyone is told by their peers there is a god (their peers god) and it's real and the peers offer "facts" from the bible to PROVE they are right. Theists have faith in their peers in both the truth of their god and their scriptures. By the time they have "faith" in their actual god it is a delusion based faith and their only real faith was in their peers.
An atheist can challenge them to prove their god against facts the atheist provides time and time again and get no direct answers or acceptances of the direct challenges, merely irrelevant lies and subterfuge because they don't have enough faith in the existence of their god to accept them. They don't have enough faith in their god to think it will give them the answers they need which is why we know they lie about their having faith in their god via proof they actually believed or via experience or via a personal relationship with it (as they claim) because not one of them has enough faith to get a sustainable answer which their god states in the bible it would give (faith of a mustard seed).
We know from the fact they only seek answers to scientific questions on lying theist sites created for the gullible and willing to lie, that their faith in their god is so weak they are too scared to even look for the truth on a genuine current scientific site. No atheist is too scared to look at a bible for fear of finding any truths.
There is no such thing as "faith", there's delusion and that is abundantly obvious.
