[MCU] How is it possible that only Hank Pym discovered the pym particles in the whole universe?

How come other intelligent creatures with more advanced technology(and maybe brain) haven't discovered their existence?

We don't know that some alien species hasn't found them.

We only know that Pym found them and was working with them. We also know that Pym found that unshielded work with them is... detrimental to mental well-being.
