The "face" is just shadows created by mountains on mars. It isn't real.
An advanced alien race that could travel to earth from mars would've left remnants or artifacts on the surface.
The face is shadows.
We don't know what traces, some alien group would have left.. we don't know that anything that was left hasn't been buried by now.
How the hell would Aliens even communicate with us?
You're assuming that it would be impossible. We communicate with dolphins and chimps.... Why couldn't they communicate with us?
They aren't aligned with the stars that they were meant to anymore, because the sky has changed, and the stars that they were "aligned" with are ones that have religious significance to the Egyptians. Humans have aligned stuff with the stars in multiple different cultures. that isn't new.
Not knowing the real "purpose" of pyramids doesn't have anything to do with the topic at hand. I think we can all assume that they have some religious or ceremonial significance to the egyptian people.
Either way, it's pretty amazing that they built these structures to match the constellations. And we don't have to assume, They wrote that they built them on one side of the nile, for the pharaohs souls. They aligned then with the stars that represented their gods.
I think we can both agree a society that can manipulate hard metals at will is more advanced than one that can only manipulate stone.
You can simply melt metal, beat it, or bend it... it's structure makes it easier to manipulate than stone. Most shyt in ancient Africa.... and the Terracotta Army in China... things in South America are hard as fukk to reproduce today using the materials they had back them. the Terracotta Army would have been much easier with materials other than stone or clay.
Again, WHY would aliens come here to build pyramids? It doesn't make sense no matter how you spin it.
Who knows if Aliens have ever came here.... but if they did come and build structures.. what makes you think the purpose would make sense to us now???
Humans built the pyramids. That isn't a "theory". And we essentially KNOW how they constructed them as well. You can go walk around Egypt and see remnants of "failed" pyramids where they were trying to learn how to construct them properly.
We just know that it took thousands of workers. Besides that we have conflicting theories. Not one group of archeologist, engineers or scientist have studied them and said , "yup, clearly this is how it was done". The quarrying methods, the engineering, the extensive planning, and placements are still being studied.
How did they do this in less than 20 years.. with caves, burial sites, deadly traps, huge blocks... while the wack ass Notre Dame Cathedral in Paris took cacs 200 years to build.
