I would comment here that this is a similar situation which causes similar feelings of frustration; we get bogged down in a back-and-forth with no discernible progress about trivial things. After much time spent on induction here, we're just where we started.
When we get trapped in such discussions as "how do you KNOW the sun will rise tomorrow?" then we are being distracted by rhetoric. We don't know with absolute certainty, but it is a reasonable assumption because there is nothing stopping the earth from spinning or the sun from shining in the foreseeable future. That's that. Inductive reasoning isn't always conclusive or correct, but sometimes it is a useful shortcut.
Now we should move on to more productive lines of thought, but we don't. And that happens often when religion is being discussed. People will for centuries divide themselves into factions over the most trivial of disagreements, and they won't budge or acknowledge that they agree 99.99% of the time on the rest of the issues. It only matters that they win this argument. And then it becomes the only focus of the discussion, when in the scheme of things it does not matter. And the larger and more pertinent issues, such as what is right and what is wrong, and why, are overlooked.
Another reason why people should simplify things. God is unknown, IMO and based on evidence and reasoning, it is likely an imaginary concept. But regardless of whether it is or it is not, that does not justify millennia of hatred, distrust, or persecution. And regardless of whether it is or it isn't, and especially since we can't conclude anything without God doing something to prove it exists, the point should really have been moot all along. There can be a side discussion about God and what proof there is, but it isn't a side discussion, it becomes the whole point for people. The only point that matters for some is that there is or isn't a God; it doesn't matter that you and the person next to you agree on most other things, it only matters to you that they think differently than you on whether or not an unprovable assumption is true or false.
That's part of the annoying absurdity of all this. Who cares? You can't ever win this debate. You will never prove God exists, only God could do that, so why are you wasting your time? I can spend a few moments of my day showing why I don't rank God's existence as being a very likely scenario, but after that, I move on to bigger and better issues, like... how should we live our lives, what is ethical, what is moral, what is right? And these are things that the faithful and the faithless should be discussing. These are things which I believe can have conclusions to them. Murder is easy, capital punishment is not, but I believe we can reason things out as a people.
The problem is that God isn't proven, and likely will never be proven either way, but some use God to justify their arguments. It isn't a logical justification, it's an opinion. And everyone has opinions. We can shout back and forth all day about our beliefs, but with nothing to back it up, and no logical or rational foundation upon which to base our arguments, we are turning red and wasting our breath for nothing.
In the meantime, just because you believe in God doesn't mean you can't use logic and reason and evidence to argue your opinions about other subjects; and that is where discussions about what we "should" be doing with our lives should be confined: in the realm of reality that we can see/taste/touch/interact with/hear and prove, with real consequences. It should be based on intellect, not faith.
A lot of bad ideas have been based on faith. A lot of them. Reason has led us to reject many of those bad ideas. Reason has led us to a freer, healthier, safer, richer, moral society. Those who state an opinion, make it law, and have no justification for it, or have really baseless or irrational justifications for it, have made the world worse, and they continue to do so every day. Such opinions as racial superiority, for example... the unfounded belief that people of different cultural or genetic backgrounds are inherently superior to others. It's not based in reason, but upon faith in one's own opinion, in spite of the facts. Such opinions as divine right, the belief that one has a right to do something because "God wills it", which has led to the installation of imperialistic dictators ruling for life, slavery, and conquest, just to name a few.
Basing our decisions on faith alone is a very dangerous and often disastrous way to live. The dangers are at least twofold: Firstly, if you don't base your decisions on facts, or on predictable or provable things, then the consequences will be much more unpredictable; chaotic; dangerous. It is like closing one's eyes while driving down the road. Being ignorant to the facts on purpose is like choosing to be blind. Faith does not help one steer.
Secondly, you cannot be reasoned with, if you rely purely on faith. Faith might cause that driver to ignore warnings that they are driving into a tree, because they have faith that they can drive safely without looking. Faith being the sole justification for things is the same as having no justification.
So, if faith isn't a source of wisdom, morality, or intelligent decision-making, why do we govern ourselves with faith?
Perhaps faith does have its purposes. I have faith that humanity can make itself better, even when things seem to get worse at times. However, I do not rely on that faith; I do not count on it. The best path forward is to use reason to help that process along; don't simply wait on the sidelines praying and wishing for things to improve. That's faith, and it's the same as doing nothing.
If you absolutely must pray, then fine; but do something FIRST. Make a positive change first, and then hope that it helps. Faith alone does nothing. I argue that faith does nothing except give people hope, and hope affects nothing except one's attitude. It can also give people false hope, and that can lead to unnecessary failures.
It's obvious that we should not base our arguments and decision-making on faith alone. And since one can arrive at the same conclusions with or without faith, it doesn't really matter who has faith. So let's stick to reason. Let's solve our problems rationally, since reasoning at least gives us a common, real framework upon which to lay the foundation of an argument or hypothesis.
When we finally stop arguing over minor technical details of rhetoric and debate that don't matter in the grand scheme, and finally stop debating the unprovable, and move on to more productive lines of thought, then I might have more to say. Otherwise, I really feel the discussion is futile.
