EASY there, big guy; I'm all for Science too but you have to admit that knowledge and long periods of observation of such things as cycles {found everywhere in nature} are every bit as valuable.
These:
were all made without modern Science {computers, satellites, orbiting devices, etc.} and the point I'm trying to make is, although the Eskimos and Inuit peoples didn't build pyramids { as far as I know} it doesn't make their long - time observation of the sky unworthy of our attention.
The guys who designed those pyramids were just looking up at the sky too, is what I'm getting at.
