<human>: Condense the text into a few key points

I'm an 18 year old senior in high school. I personally do not believe in a god of any kind. I feel like this is because I am enrolled in 2 AP science courses, and I have been a part of many a science project since middle school, so physical evidence and data have been a huge part of my learning since my early teens. Because this has become embedded in my mind, I look at everything with a bias towards the scientific explanation, and I don't believe that there have been enough regular, provable miracles performed by a god to convince me that one (or multiple) exists. However, this does not mean that I reject the possibility of a god existing. If someone can definitively show me that their god performs the miracles they claim, I will have no problem accepting that god as my own.

Now, I have both religious and non-religious friends and I have repeatedly asked them this question, but I never get any satisfying answers. They always respond with "that's how I was brought up" or "Because fuck yes." My guess is their too lazy to actually think about it or no one has ever really made them think about their own beliefs.
So I have come to you, redditors of the world. Why do you believe in what you do? Have these beliefs changed at all throughout your life? Why or why not?

Please, please, please keep any debates from getting heated. I don't want to anger people, I just want to find out why you believe.

Thanks for reading and responding (if you do)!
<bot>: I do not believe in a god because it doesn't seem scientifically feasible to me. Why do you believe in what you do, and have your beliefs ever changed drastically?
