Front of the moon where everybody could theoretically see it, or back of the moon where we need to trust sattelite pictures and computer-generated images?
Plausability/believability for front-of-the-moon would be <25% at best. Everybody with 1.5 neurons would be harping on how come "they" didn't see it when it landed there.
Plausability/believability for back-of-the-moon would be >75%. Everybody with 0.75 neurons would be quoting every sci-fi story, movie, and tv show to "prove" how it happened. And they could name the alien beings responsible in 4 notes!
Jules Verne had to wait until two folks bought & read his stories and then for a third to overhear them discussing it, and for newspapers/letters to spread the word. Orson Wells had to rely on the popularity of "Fireside Theater" for an audience, and then for the networks to pick up on the reaction/response.. With Facebook & twitter & the rest of the internet The Abominable Snowman, who is still stuck with dial-up, will know about it in mere hours - and then send eight walls of text (each in 15 parts) proving his theory is the correct one.
Yes, I have faith in humankind. More's the pity what I have faith it will do.
stay safe.
