Earth is billions of years old. Man has existed for millions of years even by unvarnished conventional wisdom: https://www.palomar.edu/anthro/hominid/australo_1.htm
Welllllll, I have been going on and on about prepping for the next worldwide disaster. Looks like I can stop. This video is too long. But if the uber rich are building under ground bunkers, they may not be happy being buried under water and debris.
The Earth is much, much older than several million years old. It is BILLIONS of years old. There are some who claim that there were very advanced civilizations in the past, BUT nowhere close to millions of years old. The oldest known civilizations are only 4,000 years old. As for the artifact, it COULD be most anything. Most likely sea shells. In order to produce tiny FUNCTIONING gears, extremely precise equipment would be required.
That turns out not to be the case. We've had confirmation of civilizations going back 12,000 years or more for several decades now. Even the first 10 minutes or so may be enough to recap what archeologists admit today.
Either way, this old mind has enough just dealing with pass few 1000 years. If I were younger, I would likely enjoy this, but now I don't store info like I used to.
Many places seemed to have these strange stone walls made of gigantic stones that interlocked with each other and no space in between. They were not put together with mortar, the stones (or what seems to be stones) were fitted together perfectly, even though they were all irregular shapes. Some people think that they are made of something that was poured, like we would pour concrete. This picture shows four different places where this kind of wall exists, but there are others, as well as roads (like in Angor Wat) that were made from this type of molded stone.
Any civilization that works with stone is going to develop ways of cutting stone to fit precisely with its neighbors. It's only a matter of time until people figure out how to the cut stone so precisely. Moreover, when a civilization has nearly unlimited manpower, ie; slavery, it is not hard to imagine that labor is not factor. Additionally, people around the globe were as intelligent as we are. Take the development of samurai swords as an example. By taking a smallish block of steel and heating it red-hot, and then cutting it almost in half, and then bending it until you end up with TWO LAYERS, Repeat again and again. Each time you end up with TWICE the layers. I takes months of work but eventually you end up with a thousand layers. End result ? The finest sword ever made by man.
I don't believe for one second that the "coal' if that is what it is, is 300 million years old. My goodness, that is long before most dinosaurs existed. Way, way even before the very first mammals. In any event, looking at the photos, you can clearly see that someone has made precise cuts to fit the bolt into place. Obviously this is a hoax.
Why would coal have anything at all to do with dinosaurs? Little but crappy lignite was even laid down during and after dinosaurs. https://www.uky.edu/KGS/coal/coal-ky-info-when-coal-form.php
