We have found that the ingredients for life are quite common in the universe and may have in fact arrived on this planet from outside sources.
The conditions for life to start may as well be common, astronomers are now discovering terrestrial extrasolar planets with orbits similar to our own.
It may very well be that life is not only abundant but inevitable.
(All due respect to Neil deGrass Tyson, who I just very broadly paraphrased.)
