Look bud. All those things have been answered. I am not trying to dodge these questions it's just that theists will not accept any of them. The answers are hard to grasp intuitively and are nuanced. Christians have to ability to change the goal posts when their belief systems is challenged and develop new philosophical arguments that no one centuries ago would every be able to dream up ( see William Lane Craigs view on genesis or the other several interpretation of genesis which is the most foundational part of Christianity). It is hard for people to accept that there is no one there looking out for your well being beyond time and space, that when you die you die, that the universe as we experience it is a set of purposeless constants where simplicity can develop complexity and that we are the results of this. You can't go by intuition becaue time after time it has been proven an ineffective way of seeing the world. You asked why can the trust "the reliability of your thinking". We only can in our day to to because we have evolved to and when it comes to places where we can't rely on our thinking we have a scientific method that has proven a million times over to be reliable.
Remember arguments are not evidence, the Bible is a collection of stories written down decades after Jesus ( just because it says it's true doesn't make it true in all aspects). I get that there are historical evidence for events but the details in those events may very well be false ( i.e. Jesus dying vs Jesus resurrection).
I was a Christian for many years. I actually took a deep dive Into my faith to get a further biblical foundation. That lead me to a painful process of deconversion and to atheism. I wish you luck in you journey
