When will earth have no life?

Answer 1

Eventually the sun will swallow the earth. Not in your lifetime, at least.

It is not quite clear whether the sun will eventually swallow the earth; it will most probably expand to the point where it almost swallows it. Anyway, long before it gets to the point of swallowing or not, the earth will be molten which sounds pretty uninhabitable.

This will happen 4 - 6 billion years from now.

i've read 3 billion, but what are a few billion years between friends?

Answer 2

I am not going to say it will never happen. But the time will come and we will just leave the planet to inhabit another or until our race dies out. I can assure you it will not happen for along while.

Answer 3

It is difficult to predict when Earth will no longer support any form of life, as it depends on various factors such as natural events, climate changes, and human activity. However, scientists estimate that in about 1 billion years, the increasing luminosity of the sun will lead to a runaway greenhouse effect making Earth uninhabitable for most forms of life.
