Saying that you can’t prove or disprove the existence of God has been the cop-out for the God debate for as long as I’ve been aware of it. Atheists, Christians, and primarily agnostics use this idea when it all comes down to agreeing to disagree. For the longest time, I was accepting of the idea and admitted that there was no way to prove or disprove it. It’s like you said, we just had to take it on faith. Well, I do not believe that all the people that believe in evolution believe it purely on faith. Sure, there are scientists out there that do, but the exceptions never define the rules.
I no longer accept the idea that the existence of God is neither provable nor disprovable. Everything is provable or disprovable. There is a yes/no answer to everything. You just have to define all the variables, and sometimes that is hard. In many cases it’s impossible logistically. We can prove that there are X number of human children that have been born with red hair, if only we could go back in time and count ALL of the redheads that were ever born. The task sounds ridiculously hard (or impossible?) to do, but it is definitely a provable or disprovable idea.
I find ample proof to explain why both sides of the God debate can (in their own minds) be considered correct and fully compliant with each person’s logic. For the theists, the proof is in the faith. There is no need question it because it IS true to them. Any attempt to prove that God doesn’t exist just seems like blasphemous desperation. On the other hand, atheists base their proof in their understanding of theology, the human mind, and evolution. I understand where the feeling for God comes from, and I understand why people want (and need) it. It all makes perfect sense, even down the idea that there is no way to prove or disprove it.
It’s not that I believe in evolution because I don’t believe in God. I don’t believe in God because I understand evolution.
