As much as im inclined to believe in the idea of aliens, I doubt the government found anything.
One department flys a top secret mission, another department isn't told = the department not told writes reports and declares they saw ufos.
Then historically the government would use the story to hide the top-secret testing but now they use it to draw attention away from corruption.
Hopefully im wrong but I find it interesting that 'oh look aliens!' keeps showing up during the biden administrations escapades..
