The problem with them is that they are useless without follow up. If we wants to explain how the picture defends the proof of aliens and explain in his rationale why it does, then that would be great. But stand alone pictures don't really do much.
It's like if I was trying to argue that there are no aliens and just started listing elements on the periodic table of elements. What's the correlation?
More importantly, what's MY correlation? Look, it is clear we all have our set opinions on the topic and no amount of discussion is going to change, yours, mine or anybody else position on the topic. What I found compelling was the multitude of different viewpoints out there and the reasons and rationales behind them. I, in no way, agreed with many of them, but I could at least appreciate them and find them entertaining.
