"They [congresspeople] were a little shocked that all that came out." The government can absolutely keep a secret! But it's only a matter of time. If all the whistleblowers, and UAP videos and photographs, with movement and propulsion unexplainable by current science, are somehow not enough evidence for people... just wait, your "real evidence" will come out in due time! Personally, I won't be truly 100% satisfied until I see a crystal clear video of an extraterrestrial having a conversation with a world leader! I think extraterrestrials don't want us to know about them until we are "ready". To be ready, we may need to develop better technology, world peace, and solutions to other major global issues.
