Really Ancient Aliens

A new scientific paper suggests life could have arisen as early as 15 million years after the Big Bang.

At that time, the paper notes, the temperature of the cooling universe would have been about what it is on Earth today,  So, if any rocky worlds existed at that time-- a big if-- they would have been at the right temperature to support liquid water on their surfaces, and therefore, possibly, life.
