The Earth is estimated to be about 4.5 billion years old. It is expected to remain habitable for several hundred million to a few billion more years, depending on various factors such as solar evolution and geological processes. Ultimately, the Earth will likely be uninhabitable in about 5 billion years when the Sun expands into a red giant. However, these timelines remain subject to scientific study and discovery.
