Complex life on Earth may last 500 million years longer than expected

How long  will complex life dwell on Earth? Some researchers say that it will be 500 million years in the future.

As the sun expands over the coming billions of years, Earth will become inhospitable to any life more complex than a microbe – but that might take longer than we thought.

The sun is getting brighter and expanding as it ages, and will one day begin to cook our planet before engulfing it altogether – but complex life may be able to hold on in this hellish Earth scenario for much longer than we previously thought.

Estimates based on looking at other stars suggest that our sun is maturing into a red giant, a process that will destroy Earth in around 5 billion years, but it remains an open question as to how long the planet will remain habitable. As far as complex life goes, the last standing will be the vegetative biosphere – plants, both aquatic and terrestrial. Their ability to continue thriving will be mediated in part by the temperature of the planet, but mainly by the levels of carbon dioxide, which is necessary for photosynthesis.

But  according to the book of Revelation, life on Earth will be very different.
