If not miraculous, then pretty darn incredibly fortunate for us.
So far, as we study our planet and the places we either visit directly or send our robots to, we haven’t found any other place with life on it. Finding life on another planet would be great. It would prove it wasn’t a “miracle” for life to develop, but just an inevitable developmental cycle of a planet with just the right conditions.
This is one of the main goals of all space research right now – to disprove the miracle theory.
So it might be called semantics, a miracle, or natural evolution of the universe? You tell me! Scientists would say not.
