When I was young, the big mystery of pop astronomy was: are there any other planets like Earth? And does water exist anywhere outside Earth.

At some point during my lifetime, exoplanets have been discovered and at some other point, the idea that planets, including earth-sized planets are almost as widespread (or rarefied) as stars themselves. At least 10 billion earth-sized planets in our galaxy alone.

So it seems like the Universe is full of Planets and a lot of those planets contain water.

The next logical step is that extra-terrestrial Life is just as common as water, planets and stars.

If that is the case, that means that life is a natural consequence of star formation/runtime, which is extremely interesting.

Which, if we now really think about it, is not entirely out of the question, in fact, it's quite probable.
