now as for people rationalizing away miracles if they saw them...
1. observe - a man is curing the blind with spit and mud.
2. question - why? is it in the components of the spit or the mud?
3. hypothesize - i believe the cure is inthe materials used
4. experiment - test the mud and saliva. compare with a large sample of various muds and saliva. determine if there is anything different about the mud and saliva used, perform controlled studies with placebos to see if that mud or saliva will cure more people and collect the data.
5. analyze the data - does the data support the hypothesis? no?
then back to 3.
3. hypothesize - it wasn't the materials so maybe it's the guy himself?
4. experiment - check to see if there are abnormalities in the person's body/blood, etc if given permission. check family history, check neighbor's histories, test this against a large random sample size.
5. analyze the data - does the data support it's the guy? yes?
6. publish results
of course we're still not at the conclusion that this guy was god though. after publishing and letting others observe the data and samples, if the data holds up, then we question why this guy was so special.
and on and on we go until we reach the inevitable conclusion that this was god, or his son, or whatever. if that were truly the case.
if we can prove it, we'll believe it. so far.........
