Now the article tries to link a comet that allegedly exploded over the region 28 million years with the creation of the pyramids, but really when I tried to read it, it just sounded like a bunch of nonsense. Infact most of it made no sense what so ever and was actually hard to read at points.
At the end of the article it makes it sound like aliens might have built the pyramids due to the sheer fact that humans were not around 28 million years ago (atleast they got the fact that humans weren't around 28 millions years ago right).
So, are the pyramids 28 million years ago?
Not a chance.
First, if these structures were 28 million years old, then the only parts that would be left of them would be the foundations, and what ever was underneath the pyramids. Everything above would have eroded away by now.
Infact many of these pyramids are in various states of erosion due to where they are located and are almost gone. Some of them don't even look like human made structures anymore, and look more like hills or small mountains out in the middle of the desert.

And while others are in far better conditions then the one pictured above, even they are visibly eroding away. One day they will disappear. It might take 10,000 years, or it might take 20,000 years, but they will erode into nothing one day.
Besides all this, if these structures were 28 million years old, they would most likely be in far better condition than what they are today (not only are they suppose to be surviving erosion, but also climate change, continental shift, and a whole lot of other stuff) nor would they have been built out of limestone, or any stone at all.
The article is nothing more than a prime example of what pseudoscience, and is nothing than a bunch of nonsense that tries to make it sound like aliens built the pyramids, and that they are far older than what they are when say a person with even a junior high school level of science education could debunk this.
