Good post, I think this is the basis of most peoples suspicions in the UFO field.
The problem is because it is so hard to sift through it all, you end up with both extremes.
One side calls bullshit and trusts the man completely in blissful ignorance.
The other totally distrusts the man and every government official is in fact a reptilian spy.
Like most things the truth is likely in the middle,
Even then the middle conspiracies may be such for military reasons, secret weapons, secret craft.
So the cases of real like UFO, ET Phone home type conspiracy is likely very small.
But I do personally believe it exist though.
