What did humans think they saw in the night sky?

For tens of thousands of years, human beings have been fascinated by the patterns of stars in the sky above Earth. Early on, they noticed that the Moon changed shape from night to night as well as its position among the stars.

When did people realize stars Suns?

450 BC
Many people’s work was needed to prove that the Sun is a star. The first person we know of to suggest that the Sun is a star up close (or, conversely, that stars are Suns far away) was Anaxagoras, around 450 BC. It was again suggested by Aristarchus of Samos, but this idea did not catch on.

How long have we known about stars for?

The word goes back thousands of years, but ideas as to their nature took a while to take modern form. They certainly knew how to use them for navigation long ago. Anaxagoras, who lived about 2600 years ago, seems to have been the first person recorded to have suggested that stars were far away suns.
