I know how they were built. It's soooooo simple. One single person could put together stonehenge in less than a week, if the stones were close at hand. It might take them longer, depending on how far they had to move the stones.... and one person could have moved the stones easily, across hills or fields. Mountains would slow things down... but not make it any more difficult, just slower. lol. As for the coral castle, the guy wasn't lying when he showed people his "tools". By all the gods at once! It's so simple that I'm amazed that i never figured it out. Just for the record, I didn't figure it out, I found it out. So, anyone else wanna know?
