All of this destruction and supposedly huge crater, deeper than Mt. Everest and walls reaching out to the atmosphere.... but you can barely even see any evidence of it on a topo map.

Humans are lucky to live to 100....

This shit happened 66,000,000 years ago.

Try harder next time.

You just strengthened my case, not yours.  You mock me because I question this theory over legitimate questions and lack of evidence, but like you said, we are lucky to live for 100 years while this happened millions of years ago, yet you act like you know it's true.

Rocks deposited during the Cretaceous Period and Tertiary Period are separated by a thin clay layer that is visible at several sites around the world.

Quoted:


I poked around the first 3 links and I've read several articles.  

I know there are pieces of evidence that scientists look at and theorize how these things can be.  But that's all it is, a theory.  Not one scientist can tell you for certain that these events happened as theorized.

If you look at scientific papers, you'll see so many things stated as facts and then theories are formed based on those facts.  But go look at those "facts" and most of the time you'll find those are just theories too.

I gotta get back to work but just for an example, take basically any statement in the first article like this one:



You have the Cretaceous Period and Tertiary Period.  Both of those periods in time are nothing more than theories if you truly get down to it.  How do they know these periods actually happened during those years?  And they took samples from "several sites around the world".  That is very little evidence to suggest clay layer was spread all over it due to an event. The Earth is HUGE and several core samples are really freaking small.  

All I'm saying is scientific research has a tendency to build theories on top of theories on top of theories.  The more theories that are made, the more the upstream theories are accepted without question.  

But I can say with absolute certainty that nobody really knows.  Not one single person that has ever stepped foot on this Earth REALLY knows what happened to it millions of years before.

No citation you would "accept" has that information.  Once any geology, archaeology, or other science career topic drifts into those areas, the people are quickly removed from their scholarly work and become "para-" doctors and scientists.  Same way people believing in ESP and UFOs were "para-science" but now that the .gov is out in the open discussing these "para-scientists" proofs and results, things are being said more and papers are actually being published instead of kept on the down low.

Archeologists are the worse.  Their version of history changes by centuries every 10 years and not always in the same direction even for the same location.   In short, "Official Sources" or "Valid Sources" are restricted sources since too much information in the hands of people who didn't get a doctorate is dangerous, same way a president who wasn't part of the club was "Dangerous".

There is plenty of evidence around especially in Mayan calendars and their shared ancestors back to the Inca Gods where the number of "cycles" is disputed but argued at a low of 4-6 and more, and those cycles are 26000 years each.  Similar calendars are in India and Sumaria.  They don't match up numerically due to different lengths of measurement units of day/month/year/etc, but on celestial events and other records of major geological or meteorological change, some approximation to the current definition of years can be made.  However, this is all "para-science" since nothing existed prior to 50,000 years ago that resembled modern humans, and people refuse to accept existence of other extinct creatures being our ancestors, not in the Darwinian profile, but the dinosaurs were the king of their age, smaller and smarter beings became kings after peaks of intelligence causing wasteful things settled down again (depending on how you call genocide as peaceful or not).  Inuit tribes kept records, they've all kept and shared records and they've all managed to save some information in a safe place, as their history includes the disaster and reborn events so attempts are made to try and secure something for the future survivors of whatever lies next.  Were doing it now with the Seed Vault in Norway and Clock of the Long Now in Nevada (temporarily paused at the moment, IIRC), as well as other places not publicized but rumored, lots of nuclear defense bunkers and constructions to hold tens of thousands for a while with everything needed to come out and kickstart life once safe again, or until they run out of some resource, anyway.

TL;DR - There is none other than supposition and doing piecewise match ups of known celestial events, Magnetic Creep of North Pole and possible rotation changes from asteroid strikes, and other indicators can be copied and pasted together to create many alternative histories, each as valid as our own mainstream history held so dear by The Professionals.
