Proof of something having landed is a far cry from proof of aliens.
You can claim the bar was raised but the simple fact is that the bar has so far been insurmountable right where it is.
Only a handful of men have been to the deepest parts of the ocean yet they have brought back proof that life exists there. Millions have seen things in the sky (including myself) that they couldn’t explain but not one has returned with proof of an alien life form.
We shall see.
Enjoy that TYPE II ERROR STUFF.
