How many times has humanity been wiped down to near extinction?

[CrusaderFrank]

No, it is not. You're assuming only Man has intelligence and the ability to create technology.

Man came into existence 6,000 years ago. Other humanoids never had the abilities modern man has

Modern man has been on Earth for at least 200,000 years

We shared the place with Neanderthals and giants

I like it!

Slaves hoisting a 70 ton granite block on a ramp — that can support the 70 ton block. That’s quite the wooden ramp

Dragging. Not 'hoisting'. You keep trying to put the stone blocks in the air. And its completely unnecessary. Just drag them. And who said a thing about wood? They would have made it out of earth.

They had literally thousands of men available. With almost all of the blocks about 2.5 tons. And almost all of the pyramid made of limestone. Like about 99% of it.

A 70 ton block of granite would have been a huge pain in the ass. Thankfully, that was a fraction of a fraction of 1% of the pyramids. And totally within their capability to drag using the simple machine known as the ramp.

No "Alien Levatation Beams" required. Your explantion is not only absurdly complicated. Its completely unnecessary.

Actually how long do you suppose that ramp would have to be?

For that big piece of granite? Hundreds and hundreds of feet in all likelihood, pulled by hundreds of men. And the Egyptians have both.

Thankfully, the pyramids had almost no 70 tons blocks of granite. The standard stone for the pyramid was 2.5 ton block of limestone.

All of which you already know. Which makes your "Alien Levitation beams built the pyramids" nonsense all the more absurd. You know better.

Maybe they disassembled the part of the ramp the stone passed, then construct the newer portion of the ramp?

They weren't "Man.". They were proto human. And "we" did not originate in Africa, but Mesopotamia.

Did you ever wonder why "Man" has built rocket ships that have traveled the solar system, but other protohumans never mastered the wheel, and barely fire -- and they probably borrowed that from us.

Says who?

Correction, these would have been made out of stone. The granite pieces were toward the center of the pyramid. The Egyptians would have easily been able to build ramps out of the limestone blocks and smaller pieces of rock and earth, using the structure of the pyramid itself to create the ramps.

The inclined plane is a hell of a simple machine. No aliens required.
