It is being said that life on our planet may be way ahead its time on the cosmic scale. In other words, it is premature.
The cosmos is 13.8 billion years old. Our earth is merely 4.5 billion years old. There are scientists that surmise that life on other planets out there could be much older than the life forms which are to be found on planet earth. Yet the evidence which is just in suggests that the current life is premature in the universal story.

When researchers ask the question “When is life most likely to emerge in the scheme of things?” the most likely answer is “Right here, right now!”…In a far off future, the chances of life elsewhere may be pretty high though.
Life actually began 30 million years after the Big Bang. The early stars spread the elements of carbon and oxygen which became the basis of life forms.
Life as we know it will probably die off 10 trillion years from now when the last stars fade out in a heat death. There is a likelihood of life to burgeon somewhere in between this inception and denouement of the universe.
Life it seems is tied up with the duration of stars. The greater a star’s mass, the less its life span. Stars that are three times the mass of our sun will die off before life has had a chance to evolve in their vicinity.
The smallest stars though weigh less than 10% the mass of our sun. They will continue sending out radiation, heat and light for 10 trillion more years. Thus any life that manages to eke out an existence on the planets they have in their vicinity will get plenty of time to evolve into the most complex of forms.
Therefore we can see here how life given half the chance and sufficient time burgeons and blooms. Chances of life appearing elsewhere in the universe is a thousand times higher in the future than it is at present.
The obvious question that comes to mind is why the sun is not a low mass star? Well, life on earth is premature. That seems to be the right answer to this one. Also the environment surrounding a low mass star is dangerous.
An example is low mass red dwarf stars. They pose threats to life near them (if there is any). The flares and deadly radiation sees to it that life does not grow on any planets they host in their ambit.
