Pyramids around the world share similarities in shape and structure that suggest they may have been influenced by visitors from space. Pyramids were built between 2500 BC and 350 CE in locations like Egypt, Mexico, Cambodia, and China, and all have the basic triangular shape. Additionally, mummies found within the pyramids were wrapped in a manner similar to a space suit. Some believe pyramids may have been constructed to mimic the shape of spacecraft or serve as landing areas. Ancient texts also describe flying vehicles, providing possible evidence that ancient civilizations had contact with extraterrestrial beings. While uncertain, the theory proposes pyramids could represent where ancient people came from or were waiting to be transported back into the heavens.
