"were," of course.
Except for those first two categories, I can't believe anyone actually is capable of falling for this stuff. Sure NASA hides what it knows about ET's, but that doesn't mean we didn't provably go to the moon (another disinfo favorite to discredit the truth).
Do you really believe the sun is flat too? Holy sh*t, dude.
Like the cliche goes, keep the mind open, but no so open everything falls out.
