Were Obelisk of Egypt Time Travel Devices?
It not a time travel device – it’s a device for interstellar and intergalactic travel. Humans are not native to the earth. The first ‘real” humans were transported here from a distant planet by intelligent beings (some call them gods, but I prefer to call them “angels”). They are making sure all habitable planets are seeded with “human” life and so they used these obelisks to act as “doorways” (or in literal translation “Stargate) between planets, thus greatly shortening the travel time. However, the obelisks today are no longer working as a result of those rough excavations the scientists and anthropologist did. What a pity.
