A benevolent extraterrestrial civilization is essentially peaceful and whose intentions for communicating with us are positive.
We live in exciting times, where it seems that we are on the cusp of contact with benevolent beings from other worlds. There is more disclosure happening every day, and many credible people are coming forward with what they know.
There is no doubt that extraterrestrials exist. If you try to get in touch with them using the traditional aerospace technology found at NASA, you are unlikely to get an answer. And if you are lucky enough to get through, it is because they want you to be able to do that.
