The Milky Way can be seen at night, when there is no interference from city lights. Since city lights have been around for only 100 years or so, the Milky Way has been known since antiquity.
No one founded the Milky Way. It was around a long time before the Sun and the Earth were even formed.
The Milky Way galaxy is approximately 13.6 billion years old, forming not long after the Big Bang, which occurred about 13.8 billion years ago. It has undergone significant changes and mergers with other galaxies over its lifetime. The Milky Way continues to evolve today, with new stars being born and old stars dying.
