>No intelligent beings would ever want to make a meaningful contact with a species that can't even tell what gender they are.
What if that species has no physical or mental genders? what if they're a species that rotates through physical genders with some wonky octopus-tier carnival sex appendage? Or maybe they lay ten different varieties of egg-like spawn… fuck knows..
Why impose your limited human understanding of the generally agreed upon two-gender human system unto a species that has mastered interstellar/interdimensional travel to even have the opportunity to make a meaningful contact as a claim in this case..
