I thought that's what religion is for.

logic.


Science is grounded on a few logical principles:
1) you cannot prove something unless you use math.
2) you always try to prove the opposite of what you want to find out. If you cannot find any shred of evidence, that means you have found a very unlikely scenario. Which means something different is most likely true.

if you go into the area of testing there are a few simple laws. In other area of science there are other laws that are all logically deduced.

according to testing theory there are some simple laws:
1) there is a real value
2) real value= value we see + error
3) IF all the errors are random, the more tries we have the more we can ignore the error (because sometimes its more and sometimes its less than the value we see)
