Friend yMy guess is as much right( or wrong) as yours. There must be at least a few of such planets in this total vastness! The thought that we are the only special in this entire universe reeks of too much of arrogance!

Almost infinite.

try to imagine there are how many dust partical on earth
and then assume that there are that much galaxies on the universe. and if those galexies haves even one planate like earth. then we can say that there are trillions and trillions of earth like planat
the problem is our science has not devoloped up to that level yet. it took us three days to reach the nearest satelite moon. and the nearest galaxy is 4.5 light years away so it would take us millions of years to reach that place

It is just .. an example that how powerful is the Supreme Soul is..

When we reach the Limit..or last end of our super thinking mind..
Then only his(Supreme Power) premises or area Start's ..

Our Science yet to find out all the things or data beneath the Sea. ..
How could they explain "from where the internal powerful flow force of Sea.comes.. ?

Then how could we.. do able to .. find the Limit.. of the Space..

The Only Solution is .. to be connected ourselves to the Super Powerhouse..
To get Lightended..
Just like a River is not remain as River unless until it meets the Sea..

Jay ...Maa .

Total number of galaxies in universe * Probability of finding a star that has planets around * probability that the star has planet as a distance from it, so that it can become solid. * probability that the composition of that planet has become similar to composition of earth.

Does it make sense?
