How has the atmosphere changed over the last 4.5 billion years?
Due to photosynthesising, single celled organisms, the atmosphere now has much more oxygen in it. this is possibly the most important change as with out we would exist. The atmosphere originally had much more carbon-dioxide and made the planet so hot humans would not be able to survive.
How long is the sun going to last?
The sun is expected to last for another 5 billion years. It is currently in the middle of its main sequence phase, which is the longest phase in its life cycle.
How long has the sun been in existence for?

Can stars shine for billions of years?
Yes. Most stars do. Our own star, the sun, is about 4.6 billion years old and is expected to last for about another 5 billion years. The smallest, slowest-burning stars are believed to be able to last for trillions of years. Giant stars, which burn quickly, may only last a few million years.
How many years would the Sun last for?
The Sun is currently about 4.6 billion years old and it is estimated to have a remaining lifespan of about 5 billion years. After that, it will exhaust its nuclear fuel and undergo a series of changes, eventually ending up as a white dwarf.
How have the levels of gases in the atmosphere changed in the last 4 billion years?
The composition of gases in the atmosphere has evolved significantly over the last 4 billion years. Initially, the atmosphere was primarily composed of carbon dioxide and nitrogen. Over time, organisms like cyanobacteria produced oxygen through photosynthesis, leading to the rise of oxygen levels and the formation of an oxygen-rich atmosphere. This transition enabled the development of aerobic organisms.
