Reasonable to who??? To you? To me??? What a sliding scale that is. Most reasonable beliefs are based on faith. Go to dictionary.com and look up faith. What's the very, very first (most common) defintion? Trust. It says nothing about proof, evidence or anything else. This is what I refer to as evidenced faith. Just because you disagree with my interpretation of the evidence, doesn't make it unevidenced.
I have yet to meet an atheist or agnostic who doesn't reasonably believe what is reasonable to believe and who doesn't believe what is unreasonable to believe.
Now you're sounding like Rush Limbaugh. I guess I'll just check with you to find out if my belief conforms to your level of reason. Hogwash. Reasonable people disagree all the time. That's OK and to be expected. You'll never by my arbiter of what's reasonable or not. Get used to it.
Are you one of those who insist that it takes the "wonder working power" of faith to attempt to crank the car in the morning since there's the small possibility it won't crank?
Not really. I'm the one who insists that slamming on the brakes takes more than a bit of faith and that faith is often crushed as is the front of a vehicle. It's takes faith to believe or disbelieve in any esoteric concept. It takes faith to believe in evolution. I most certainly do though I've never seen something evolve in front of me. My inspection and study of the fossil record indicates that the hypothesis of evolution is true.
The only person to be able to claim to be mostly free of faith is the true agnostic. As I posted before: I have yet to meet one. Most people are biased one way or the other. Their belief or disbelief is based on emotion, not verifiable fact.
