wrong concept you providing us How you can say that if intersection of infinite no sets is empty how you say that the family of same sets with finite intersection also empty. For easy example let A1={2,3,4} A2={3,4,5} and A3={5,6} then intersection of A1, A2, A3 is empty, but intersection of A1, A2 ={3,4} and A2, A3={5}. You are wrong pls read and then teach us

The contrapositive of P -> Q is NotQ -> NotP. So isn't the contrapositive in the forward direction: Given any family of sets without FIP and intersection of the entire family is empty, then that implies X is not compact? Seems like the theorem being proved is that: A finite collection of closed subsets F have nonempty intersection the intersection of all closed subsets of F have nonempty intersection? So seems like the arrow is in the wrong place on the board?

If finite intersection property fails then how can you say that X is compact??

Squiral nuts the intersection of A3 and A1 is empty so the collection {A1, A2, and A3} don’t have the finite intersection property.
