But a educated guess, by definition, implies a level of uncertainty. All eyesight is, is our brain interpreting light reflecting off various surfaces. A blind man who has just gained the ability to see would not yet know how to interpret what he sees, because his brain had never had the ability to process the information before. Just the same way all of us know that 2+2=4, but to someone who has no idea what numbers are, they'd have no clue.
