How many life sustaining and habitable worlds are there?
According to the recent understanding along the lines outlined in the OP, there are anywhere between
200 billion TRILLION - to two trillion trillion such planets in the known universe.
I'll come back and post the math to support this, and to show that it's a relatively conservative estimate at that, pegging the number of such planets in each galaxy between 1 and 10 million, with there being 200 billion galaxies (approx) in the known universe.
That's 2 followed by 18, or 17 zeros if you would rather take the conservative estimate of only 1 million such worlds, ave, in each galaxy, on average, instead of 10 million (18 zeros), when it's quite possible they number in the billions (add 4 more zeros for 100 million and then to a billion) per galaxy, especially when moons are included as planetary bodies some of which are capable of "housing" life.
Doesn't matter how you slice and dice these kinds of numbers, either way the number is incredibly HUGE!

And the truth, let us remember, is probably rather solipsistic no matter who or where you are, whether a human being on planet earth, or a schmorg on (inpronouncible).

It's all part of one great process, and our ability to observe it all and marvel at it all, and reflect, that's really something, it changes everything, the awareness of the beauty and magnificence and the almost miraculous nature of the great mystery of all time - that's special!

would you rather get the opportunity to experience existence as a man, a pigeon, or a giraffe?
