So obviously it was yet another charade. The poor "guy" couldn't communicate anything, much less complex astronomical science.
Two options, I do hope for him the first one is what happened, and not the second one:
1. He died of ALS some 60 years ago, and they used a veritable puppet instead (when you look closely you see "he" kinda looks like one)
2. He never had ALS, he wanted to come forward about NASA's et al lies, tell the world the truth.
But, they could not have it. So they poisoned him to the point all his faculties declined to almost zero, but he was kept alive as a living puppet.

Whaddaya think?
