There is no life form that can occur separately twice on this planet.
Charles Darwin stated that negating this statement
with but a single example renders his theory completely false.
In fact, it would be a counter example to any Proof of Evolution,
thereby rendering it logically invalid.
Charles Darwin goes to great length explaining, for example,
how an arctic plant could migrate to the antarctic during an ice age,
and how plant seeds can migrate on floating tree trunks and icebergs
to distant islands.
There is no reason to think this law is not literally universal,
which means life can not occur separately twice in the Universe.
Yet, there is no reason to think it occurred on this planet.
We could have been a handful of amoeba lookalikes,
frozen with our own water supply,
migrating on a meteor through space to the next planet.
