I noticed in this article that the Chinese came to the same possible reason for the pyramids as I posted some time ago, viz,. that early ships landed on top of them to recharged from the Earth for flights home. I think that later models have got their recharge, from the Earth's atmosphere, via electrical storms. It has been seen in NASA videos that electrical storms attract alien ships.
So pyramids are beaming bolts up into space towards a huge cloud. Is the cloud perhaps a cloak under which a number of ships travel? Does the cloud blow along on some celestial wind and the ships just piggy back along inside, perhaps. ? This would save a lot of fuel. As the near their destination, they may need a quick charge to power up.
So if this is so, they have obviously been here before to have had the pyramids built by labour and are now returning soon.
