The Tuesday/Monday example being arbitrary is my point, glad you pointed that out. This is the casual way that I “have faith” that there is no God. In my eyes your choice of deity to worship is just as arbitrary, there are thousands of religions. The fact that some of them promise “hell” to “sinners” is not a reason for me to operate as though these things are true. There are just as many if not more spiritual practices that have nothing to do with eternal damnation, why would I operate as if any of these are the reality when they’re all claiming to be The One Truth? I’m expected to pick yours just because you said so? That seems silly, and it’s also silly to call this thought process “faith” I think.
Regarding the dinosaurs, we have fossil records, and that’s a bit different than “God is gonna getcha, better be a good boy, believe me bro,” but I do in fact believe that Jesus existed, because we have extensive historical context and documents talking about him. As stated elsewhere this is sufficient to generally consider a person to have existed. Most historians also claim as much, and I’m not a historian so I will defer to the experts. Whether or not he is the Messiah though, and has magic powers as stated in the bible, is a much more ridiculous claim. When you tell me a reality-bending zombie that is his own father exists, the burden of proof for that claim is much higher than “Did this person exist historically?” This is the point that FlyingSquid is making, which I agree with.
