Here's my logic.
Remember the ball that falls through the wooden plate with nails? Every time the ball comes down in a different way and takes a different path downwards. Its random.
Well..not completely. Minor differences in wind changes, gravity, and other enviromental aspects will affect it, yes, but we call it "random". if there wasnt a single aspect to influence it, the ball woudnt even move, or stay put on the absolute top of the first nail. Or even better: there woudnt have been a ball at all.
My opinion is, there is no such thing as complete randomness. It doesnt exist. Everything in this world has a reason for it to happen one way or another.
But here comes the problem! the reason for sóme things to happen however, we can't explain. And that is where the word "believe" comes in. You "believe" that "this unexplainable event X " happened because of [ solution A] or [ solution B].
That is also why it's an endless discussion. The unexplainable. Some people call it Religion/God, some people call it "where sience hasnt come yet". Because Science or God, they are both believes about the unexplainable.
However, the only "advantage" science has over religion is that it's flexible. For example: We say that there is "literally nothing" between molecules. If some guy shows up with a research saying "look through this gigantic microscope showing there are little smurfs in between!" then we say "well...ok...f*ck it, smurfs it is then."
And there comes my last point. Why is there no Religion with a theory contradicting any proven scientific thing? It sounds weird and suspicious to me that the church changed its intrepetation of "the creation of the universe" after people discovered the earth is nothing like the centre of the universe. I am afraid that the future will only continue to bring down Religious fundaments by new scientific proof.
However, If scientific proof will be presented that has the conclusion that there is zero possibility of us people going to heaven or hell, because "sciencewise" there is no chance of it existing, it probably woudnt convince ONE believer in God to think different I guess. And that's weird to me as well, given the fact that Christian Fundaments (like God/Heaven/etc) are mostly based on things that havent been proven yet.
Conclusion
In my opinion, Religions like Christianity fit "just a bit to good" in the situation of "what we don't know yet". As history has shown us before....Egytians also tent to believe that the Pharaoh was send by the gods and therefor it was invincible. Well, I think that we can all agree on that beeing not true. But back then, people coudn't prove it wasnt true at all. It was "unexplainable" at that time and therefore "a believe". Why wouldnt Christianity have the same fate, if all other old believes have been proven to be not possible?
I think you understand by now that I personally don't believe in God. But let me finish this post by saying I truly admire Religion in general, how it brings people together. It remains a beautiful concept.
