I checked to see when Khufu pyramid's latitude would perfectly align with the galactic plane and I ended up with the year 1480 AD. But this is the gematria value of Christ!
XRISTOS = 600 + 100 + 10 + 200 + 300 + 70 + 200 = 1480
Also art 1480 AD Christopher Columbus's first child was born. Interesting how this date aligns with Columbus's time span. Christopher means the bringer of Christ. It seems that he was in contact with sacred knowledge - maybe maps at Chios island before sailing to discover America.
