I've only ever seen these pyramids in movies, I'm being honest, hahaha.
When it comes to analyzing how these people worked on these pyramids, we know that many people were involved, but the master builders, so to speak, were highly skilled in their work. Can you imagine if they worked with today's technological advancements. From this, we deduce that human beings are very intelligent, created in the image of God. Those who say that extraterrestrials were there are possibly misinformed, or perhaps we're giving this idea a degree of probability. What do you say, ¿humans or extraterrestrials? I say both, hahaha.
