There are numerous written records detailing how and when the various pyramids were constructed, the materials, number of laborers, techniques etc. This is just one source of literally thousands....including pictographs within the very pyramids themselves. They're also supported in the archeological record as they found various tools, blocks, pottery, ports etc. that corroborates this.
There is so much proof that the Egyptians built them, you might as well claim we just found Hoover dam in place where it is as well.
With carbon dating, you should know the age of the pyramids or other structures and then match it to the impact crater that wiped out these advanced global civilizations, you know like they did with the mass extinction of the dinosaurs. That would be the very first step before making such a claim.
Main stream Egyptology is full of crap, imo. "There are numerous written records detailing how and when the various pyramids were constructed", you say. Written by people with an agenda! I wont even click a link called History.com, lol.
Again, all around the world there is massive evidence of a civilization that predates our understanding of the far past. The Dynastic Egyptians did not build the Great Pyramids with their primitive tools.
There is water erosion on the Sphinx, and other areas of Giza; and casing stones that resemble stones in PERU! All that I'd wager History.com ignores.
On topic: The Hiawatha Crater found in Greenland just might have been the catalyst of the disappearance of the knowledge that built the Great Pyramid to Machu Piccu. I believe hunting Near Earth Asteroids, and comets is a worthy venture. As you know, as a Mathguy, a newly discovered NEA orbit can be accurately calculated, and modeled (resisting slamming climate models), therefore a solution can be worked out to avert a close encounter with Earth.
This YouTube channel has a lot of great videos of mostly pictures from around the world that shows so many places that are extremely ancient and perplexing. Here's one of Giza...
We will all feel pretty foolish when an asteroid hits and causes hundreds of billions of dollars in damage that could have been avoided with a few hundred million in funding for planetary defense.
Depends on the size of the aforementioned asteroid, after a few hours it'll pass, we won't feel foolish and all will be cleansed.
First off, any space war tech wouldn't stop one from hitting earth after it was intercepted. It would only fragment it possibly making it worse. Anything of actual value to the planet would have to be much farther out in orbit and the logistics of that seem impossible today.

I've actually read that they think they can intercept them with vehicles that could attach to asteroids and provide enough energy to alter their course via some some of propulsion system.
But concern over the impact- asteroid issue seems to be pretty high in those who study space and the solar system which only means that we will soon develop an impact- asteroid denial community soon.
I'd say a guy who was a research scientist for MIT's Experimental Astronomy Laboratory, ran the operational part of a satellite communications network and co-founded the B612 non-profit can probably hold his own when it comes to understanding the orbital mechanics involved in nudging asteroids. MIT doesn't hand over master's degrees as participation prizes.
What are puny little humans going to do against a million ton rock traveling at 1000 miles per second?
It wouldn’t weigh anything in space. Planet or moon sized though and ya we’d be effecd. Would need deta v in the millions.
The movies mislead, all you really need to do is offset the orbit(for a reasonably sized astroid). Have the probe rendezvous with the rock push its orbit into a prograde direction to increase its velocity into an escape trajectory and it would skip earth, or maybe even push it into orbit to be studied.

Weight is irrelevant. A space rock's mass (plus speed) are what matter. The more massive, the more damage it can do and the harder it would be to alter its course. An asteroid the size of a football field would strike with more power than the largest H-bomb.

They're orbiting the Sun, not the Earth, and we don't need to push them out of that orbit, just nudge them a little so they don't hit us.
Say that the meteor or comet is a white male; the left would go all out in finding a way to destroy it.
