"I saw this documentary where a team of archeologists tried to raise a small Egyptian-type obelisk using only contemporary equipment. When that failed, they used modern pulleys. When that failed, they had to admit their theories were wrong. What am I saying? I don’t know."

I think I know what you're trying to say, so allow me put it in to words:
"The so-called 'experts' don't have a freaking clue how these giant obelisks and boulders were moved." And I don't either.

IIRC, Heyerdahl, being among other things a practical man, tried out the methods he thought they used. (could be wrong, could have been someone else, later.) SOMEONE succeeded in using rollers, palm-fiber rope, etc., as I've seen pictures. —— Wikipedia says it was a Charles Love.

Another guy has his own theory, and a scale-model demo video: http://www.tegakinet.jp/moai.htm

We could always hold a seance and ask.
