There is a basic flaw in your argument. You say you KNOW there is a god. Your entire argument assumes a god is real and that evidence is just not able to corroborate it. But that begs the question how you know god is real in the first place. You claim that you know because you have a personal experience with god. But we KNOW that a lot of those experiences people have claimed are hallucinations or misunderstandings of what actually happened. We also know that literally everyone in every religion has claimed to have an experience with their god that makes them know it is real. They cannot all be right, every single person in every single religion other than yours must be either a) lying or b) delusional. It is unlikely that everyone is lying (so unlikely it borders on impossible). So they must all be delusional except for your religion. But if this is the case, you have literally no reason to assume you aren’t one of those that is hallucinating. There is also no reason to assume that anyone is actually correct. It is likely that your religion hallucinates or personal experiences with god just like what you already believe every other religion does.
Also, this is something I want to clear up because I see this mistake all the time among theists. NOTHING is beyond science. Things can be beyond our current technology or even perhaps any technology we will ever achieve. But science is a process, not an entity. The process of science is the only reliable way we have to observe and expand our understanding of the universe. If the God you believe in is real, they made a real, objective impact on the physical world and humanity. They are a real sentient being. There is absolutely no reason to believe that such a god would be beyond science.
You do not KNOW that your god or any god exists. You believe it does based on how you were raised, where you were raised, and what you want to be true. This is evident because of how clearly religion is locked to location and circumstance of birth and childhood.
Finally, you claim that god is similar to emotions and feelings, not objectively verifiable other than personal knowledge. But that is a completely loaded argument. Emotions are subjective. The god that you are so sure exists can’t be subjective. It created and changed things in our physical universe. It is a sentient, being. This is something that needs to be objectively backed up with evidence, otherwise, it is literally a fairy tale no different than Santa Claus or the Easter Bunny. You think children aren’t convinced they’ve seen Santa Once? Or his work? Of course they think they did, that doesn’t make them right!
Morality is not anti-science actually. But it isn’t a science in the way you think it is. There is no such thing as exact, objective morality. It is actually a very interesting field of science. The study of how our morals came to be. All of our morals came from evolution and cultural progression. They have been discussed, debated, and thought out. They have changed as times change. Interestingly, religion is the opposite, it says there are strict morals that exist that will always be true, no matter how much time passes. I don’t really get why bringing up morals helps your case at all, it is just another example of something in the Bible that assumes there is a god and shapes rules out of fear of a fictional deity that will make you suffer if you disrespect them. The origin of morals is actually relativity basic.
Moving on from morals and back to the question at hand: It really is this simple, to believe in god is to act as if you are 100% sure something is true despite having absolutely no reason to other than here say and what you want to be true.
