For a start, there will still be some general information if someone does not know about these very sarcophagi.
We found quite large granite sarcophagi in the Memphis necropolis, in the amount of 24, at least these are those that are officially known, after all, something may be hiding.
As far as we know, the largest sarcophagus has a weight of 100 tons, while others weigh 60 or slightly more. Although it seems to me that the weight of the sarcophagi is more, since it is granite and they look quite large, it is not important.
Now it is worth approaching the processing of one of these sarcophagi, which was studied literally up and down, discovering a lot of interesting and impossible things not only for primitive instruments, but even for our civilization.
The first is the very fact of granite and its level of processing. You can see how everything is perfectly polished, the sides are all equal and everything is processed to the exact size.
It is worth noting the processing of the lid of the sarcophagus itself. I very much doubt that this can be done without precise calculations and high-tech devices.

But according to experts who examined one of these sarcophagi, the most important feature in the processing is the right inner corners.
As far as is known, right internal corners in a monolithic blank (from which the sarcophagus itself was made) is impossible to make even now. At least what tools can be used to do this - many experts find it difficult to answer.
I think anyone should understand that no slaves and manual work will be able to create even some of the work and level of processing that is in these sarcophagi.
But there are some other mysteries that I will briefly cover. According to the official version, the sarcophagi were built for bulls and there is no point in telling anything about this version, since this is complete nonsense.
But the issue of transportation is already much more important. As strange as it may seem, only one entrance to the necropolis was found and it is smaller than the size of the sarcophagi, which is why no one can explain how they got there at all.
But even if this entrance was large, how to move such a sarcophagus inside, along the corridors, no one can answer either, since people could not have such power, even if they were hundreds of slaves.
In general, the level of processing of granite sarcophagi is at a high level, and who, when and for what made them, is now impossible to answer. Although for several years information about the sarcophagi simply disappeared, which means that everything that would be interesting and contrary to history could have simply been removed, however, as in most cases.
