It would have probably had a big effect. Something I am amazed by is how accurate celestial navigation (using the sun, moon and stars) was for hundreds of years. It was still the most accurate means of navigation outside radar and visual range of land in the 20th century until GPS came along. One of the most important breakthroughs was being able to accurately determine longitude at sea and of all things it is rooted in the time difference between the highest point the sun reaches where you are and noon in England. That is where GMT (Greenwich Mean Time) comes from originally, and lead a surge in developing very accurate clocks. So imagine how much history would be different from having a different sky.
