Maybe AATIP doesn't know, but the classified Blue Book files sure as hell do. Numerous indifferent witnesses report a variety of species, and some craft are best described as tourist shuttles. Earth is a petting zoo, without the petting, but definitely animals.

What counts is the alien interest in our military capabilities.

As for those who still don't know if space is traversable, we have Ben Rich's statement: “We now have the technology to take ET home” (UCLA speech by Ben Rich, now deceased, former head of Lockheed Skunkworks).

Honestly we don't know if there is space traveling races.

I'll wait for the actual report.

That's because they can't rule out Elon Musk, the US Air Force, or the Russian Navy playing tricks on them.
