It's a conspiracy theory because how many times Aliens has been pictured everywhere in this planet?
That doesn't even make sense. What does someone else's alien claim have to do with a NASA announcement? Nothing is answer
Yet now NASA is going to find "Aliens" planets. Which in my opinion, need to see to believe it.
Having found planets in such excess was a huge plus in terms of odds for having life. As it stands now, in order to have life, there needs to be planets for that life to survive on. So finding all these planets means we can check off one of the qualifiers to finding life. NASA is basically "hoping" that with more and more advanced technology coming into development over the next few decades, that we'll be able to detect certain characteristics of some of these planets. Which might include being able to detect certain aspects of life itself.
NASA is one these government agencies that try to hide as much as possible anything related to Aliens creatures or Aircrafts from the past.
Ok now you're implying that they have evidence of alien life, after you just said "Which in my opinion, need to see to believe it". So do you have evidence they are hiding information about alien life or do you need to see it to believe it? As for hiding "aircrafts", they do have a history of working with the military on "aircraft". After all, NASA is a gov agency and secrecy goes with the territory.
Conspiracy: a secret plan by a group to do something
unlawful or harmful.
So I ask you again, what exactly is the conspiracy here?
