But this idea has since been discredited by scientists for a number of reasons.
1. Pyramids aren't hollow: They're incredibly solid and usually only contain a few claustrophobic chambers, connected by long, sloping pathways and concealed entrances, in order to confuse potential tomb raiders. Not a very efficient place to store grain.
2. Ancient Egyptians left instructions inside the pyramids: Archaeologists have found funerary text inscriptionsinside pyramid chambers built between 2375 and 2160 BCE, which serve the sole purpose of instructing the dead pharaoh's soul how to cross over to the afterworld. That would be a strange thing to put inside a granary.
3. There's evidence of burial inside the pyramids: "Pyramids were definitely used as tombs: burial equipment, such as sarcophagi, jewellery, mummies or mummy parts were found in some of them. (The others were robbed in antiquity, or in a few cases the burial chambers are below the water table)," archaeologistDeborah Sweeney from Tel Aviv University in Israel told Jewish news site Haaretz over email.
4. There are lots of different pyramids, built over thousands of years: There are more than 100 pyramids known in Egypt, and they were built anywhere between 2686 and 1750 BCE. South of Egypt, in Sudan, there are around 255 of the structures. All the ones studied appear to have served as tombs.
5. Ancient Egyptians actually had granaries: And they've been studied by archaeologists. "These were normally dome-shaped buildings open at the top, which stood near houses and government buildings," said Sweeney.
6. The only grain found in pyramids is part of a burial ritual: To be fair, there have been a few odd remains of grain found in pyramids by archaeologists, but this is part of an Egyptian burial ritual known as theOsiris bed, as the Tour Egypt site explains:
"These are wooden trays in the form of the god, Osiris, which were planted with seeds of grain. They were expected to germinate once the tomb was sealed, and were symbolic of the continuation of life after death."
So there you have it. We think the evidence speaks for itself. And just in case it doesn't, we'll leave you with this:
