In Ant-Man, Hank Pym said this to Scott Lang:
Twenty years ago I created a formula that altered atomic relative distance.
Well, Ant-Man's events were set in 2015. 20 years before that year was 1995.
But in Avengers: Endgame Steve Rogers stole Pym's particles from his lab in 1970.
So why did Hank Pym say that to Scott Lang?
