I believe in many things
I agree that it is a matter of definition. If you consider that faith is belief in something despite a lack of convincing evidence, then you have a tolerably useful definition that sorts theists from non-theists, flat-earthers from non-flat-earthers and those who believe in life on other worlds from those who don't. This begs the question of what constitutes convincing evidence, but to my mind, if the evidence was convincing, then most people would believe it.It depends on what you mean by "faith". If by "faith" you mean "confidence and trust" in something, obviously they do. However, if by "faith" you mean some kind of religious adherence or the theological virtue, then I'd say "no".
edit per modPresent evidence god does not exist.
