Look, I'm not an engineer like a lot of you guys (I'm in construction) but even I knew enough to see that It was hoeey. Aside from cracking up when I saw the picture, I mean.

For one, they said the drawing is made from an iron compound "found only in the highlands of the moon." How would we know that? We've never been to the highlands of the moon.

Also that "chemical analysis dates the drawing at 200,000 years." What chemical analysis is that? You can't carbon date iron.

I have to agree that given the consistency of the kind of questions or claims TINF comes up with, I suspect he's just having a little fun. Which is fine if we remember to do the same & not get too wound up about it.
