The danger in discovering the stars was that you had to be out of the cave during the night, when the leopards and bears were hunting. Proper cavemen stayed IN the cave at night, for protection. There were monsters out there!
You can't really talk about it as a discovery. People looked at the stars since times immemorial and named them. Why? Stars were pretty important for the navigation and it's surely easier to remember something if you can associate it with some object you are familiar with (cross for example).
This is possible because stars have been and being constantly produced singe it was first possible for them to form in the Universe. The current population of stars visible to us therefore contains stars at all stage/ages of existence By observation we can therefor study stars at all stages of their life, even though we ourselves have only been in existence for a shot time.
Some stars might no longer be in existence but one can still see them in the night sky because they are still active.
One of the greatest advances made by a Hellenic scholar was the discovery of the 'fixed' stars. Aristarchus of Samos (310-230 BCE) was the first to discover the vastness of the Universe by studying the pattern of the stars.

There are several reasons to believe in the existence of extraterrestrial life. One reason is the vastness of the universe, with billions of galaxies and planets that could potentially support life. Additionally, the discovery of extremophiles on Earth, organisms that can survive in extreme conditions, suggests that life could exist in harsh environments elsewhere in the universe. Finally, ongoing scientific research, such as the discovery of exoplanets in the habitable zone of their stars, provides further evidence that extraterrestrial life may exist.
Stars have been observed by humans for thousands of years, with ancient civilizations like the Babylonians and Greeks documenting their existence as early as 3000 BCE. However, the scientific understanding of stars began to develop in the 17th century with the advent of telescopes. Galileo Galilei's observations in the early 1600s marked a significant advancement in the study of stars. The discovery of their composition and processes came much later, particularly in the 19th and 20th centuries with advancements in spectroscopy and astrophysics.
No. The stars are much too far away for the Earth's existence to have any measurable effect on them.
The Nobel Prize in Physics 1993 was awarded jointly to Russell A. Hulse and Joseph H. Taylor Jr. for the discovery of a new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation
In ancient times, there were several prevailing theories about the existence of stars. While some tribes believed the stars were Gods, others considered them spirits of the deceased. Some tribes also believed that the stars were their ancestors that were watching over them on earth.
The discovery of the Milky Way is credited to the ancient Greek philosopher Democritus, who was the first person in recorded history to make the assumption that the Milky Way existed and was made up of billions of distant stars.
Most stars, for most of their existence, fuse hydrogen into helium.
