Quix, you know that the burden of proof, without fail, is always on those who make extraordinary claims.
A person setting out to prove something exists is similar to one who sets out to prove the same thing doesn't exist.They both start from a point of bias and their judgment will be so colored.
Skeptics are the mirror image of those who believe without evidence...neither approach the subject scientifically. To both, their belief is a matter of faith and/or desire...and not the product of rational thought.
