Pyramids

Due to heavy rains, the Nile water levels have risen, threatening to damage Sudan's 2,300 year old pyramids. The Nile has reached record-breaking levels, already killed around 100 people and destroyed the homes of many. According to archaeologist Marc Maillot sandbag walls have been built and water is being pumped out to protect the pyramids.

Tesla and SpaceX CEO Elon Musk has tweeted on Friday that "Aliens built the pyramids obv" (obv = obviously). The tweet has been shared widely on Twitter and received over 500,000 likes.

The Minister of International Co-operation of Egypt Rania al-Mashat has responded to the claim and denied that they were built by aliens. She said that "I invite you & Space X to explore the writings about how the pyramids were built and also to check out the tombs of the pyramid builders".

At a later point, Elon Musk linked a BBC History site that provides information about the history of the workers that built the pyramids.
