I don't know what these people are getting at here. Maybe one guy found a cross of some kind in the pyramid. I doubt it, because the pyramid was picked clean a long, long time ago, but say he did. So what? A cross is just a cross. It could be a pagan religious symbol, or it could be an architect's tool or a stonemason's tool. I couldn't listen to this whole thing because ... well, boring ... but if they are implying some Christian connection, that's just ridiculous.
