Ancient peoples used the sky for a number of various reasons- direction, time, religion, zodiac, weather and the like.
This is because the stars are so far away, that it takes the light from them thousands of years to get to Earth.
1652 Edit : That seems unlikely. Arcturus is one of the brightest stars in the sky and it must have been seen as soon as people looked at the night sky, many thousands of years ago.
today scientists use telescopes, cameras, and computers to study how the stars and other objects in the sky seem to move. we have learned a lot about the stars since people looked at the sky thousands of years ago
Thousands of years ago, probably tens of thousands, people viewed the night sky in awe and wonder. Ancient man took the sky to represent our dreams and nightmares and came up with myths and legends to convey stories to others. The sky was used as a tool to determine when to plant crops and when to harvest, when the rains were coming and when it would be dry, when animals hibernate and when they migrate. They weren't "discovered" - they were imagined and used in folklore and still are today.
Orion is not a star, it is a constellation. Being a constellation, it has many stars in it. It has been a recognised constellation since humans first looked at the night sky, thousands of years ago.

We don't know. The diameter of our galaxy is estimated at 100,000 lights years. But it is an estimate. When we look at the stars in the night sky, we are looking at how those stars were thousands, even hundreds or thousands of years ago.
the sky was founded about 4.6 billion years ago

astronomy isnthe oldest science people were wondering at the nite sky over 5000 years ago
Jupiter is easily visible in the night sky. Jupiter has been known since the first pre-men looked at the stars hundreds of thousands of years ago.

There isn't much to "discover" here - Alpha Centauri is the third-brightest star in the sky. People must already have seen him tens of thousands of years ago.
because the saw it happening. they didn't have much technology so the believed with their eyes.
Hundreds of thousands of years ago, Ancient Man would have observed the daily progress of the Sun. Clearly written records were not kept at that time.
