The more Einstein thought about Bose’s paper, the more influenced he became by its implications. The reason Bose’s interpretation produced accurate results was that since photons are indistinguishable from each other, one cannot treat any two photons having equal energy as being two different photons.

Understanding this is pretty easy: consider the situation when you have to toss two distinguishable and unbiased coins at the same time. Then there may come one of the four possible outcomes as shown by the following picture.
