I'd like to ask about the meaning of "so" in the following context:
Of the three brilliant stars of the Sirius system, only one remains in the physical realm, as you understand it from the three-dimensional perspective. This celestial fire is referred to in your scientific communities as "Sirius A." We Sirians know it as the deity, Sothis, and so it has been recognized by the ancient Egyptians, who knew so much about our civilizations and their own starseed linkage to us.
Does "so" in this case mean the same as "so" in "I was lost so I bought a street map"?
