List Question

SAT can be verified in polynomial time, by a conversion to CNF, then verifying the SAT of the CNF in polynomial. What is wrong with this argument?

How can I perform validity of ∃∀.φ, if I use quantifier elimination for ∀.φ and get φ'? I hypothetise ∃φ' solves satisfiability, not validity
