Almost nothing survives from the 4th dynasty.
This pretty much leaves us to project later ideas backward onto them. I choose
to project ideas that are nearly concurrent with their time rather than those from
thousands of years later. I choose to try to deduce which of the ideas are actu-
ally applicable to the builders and might have actually written by the builders than
to simply assume there was no change in the "religion" for thousands of years to
justify the projection of much later ideas.
I greatly prefer theories about the great pyramids that excludes everything from later
times. Skeptics often complain that alts view the great pyramids and G1 in a vacuum
but this might be why their theories adhere better to the evidence. If there were mas-
sive changes in the "religion" or "nature" over the centuries then those theories (Egy-
ptology) that do the most projecting are likely to be the most wrong.
This is all in the hands of the people who scoff and mock everyone who isn't an Egy-
ptologist. They can go out and use 21st century science to prove their contentions or
they can continue to appeal to emotions and the status quo. When the science gets
done then their mocking might hurt but until then they have no clothes.
