They say if earth hadn't landed in the Goldilocks Zone,
If cyanobacteria hadn’t produced oxygen for the atmosphere,
If we had no satellite moon to push and pull the tides,
If the dominoes hadn’t fallen perfectly to create earth’s conditions,
Life would not be possible.
But they also say that life evolves, adapts, until it is perfect for the conditions in which it finds itself,
That there are creatures thriving where we once believed life could not possibly survive,
That there are microbes that can only exist in a volcano,
There are multiple species of deep sea fish dwelling at 12,000 pounds of pressure per square inch,
That tardigrades can live in a vacuum and without sustenance for several years at a time,
That despite inhospitable conditions, life abounds.
So why do they say they are looking for another earth when life could have begun so very differently and still evolved to create advanced intelligent beings?
Why don’t they say that life has likely formed outside the boundaries of our limited understanding of the universe and its laws?
Why are they still only searching for life as we know it?
