I don’t have an opinion on faith since I don’t think it exists. Since you believe it exists the burden of proof is on you.
Believing in anything or not believing in anything is faith. To believe it doesn't exist is an opinion and is also faith because you believe it doesn't exist.
Faith is not a tangable thing it cannot be proven or disproven by conventional means just as a person having a soul or that we have emotions there is no evidence one can prove of these things except in our daily observance.
Even the fact that we have thoughts is not a physical thing but if one looks at the brain in a study you will notice that when we think deeper thoughts the brains shows much more activity when we are emotional or show emotions the brain also shows more activity than normal each time in a different area of the brain that works differently than the rest of the brain.
But when you look at the brain when one shows faith say in prayer or believing in something seemingly impossible the brain shows activity in every area the entire thing will light up under the machines that show the brain activity in such tests.
so really the fact that the brain shows activity at all when it comes to faith is evidence it exists because the brain recognizes it and works accordingly.
